RESUMO

Infertility is a well-recognized multifactorial problem affecting the majority of people who struggle with infertility issues. In recent times, among infertility cases, the male factor has acquired importance, and now it contributes to approximately half of the infertility cases because of different abnormalities. In the current study, we used natural phytochemicals as potential drug-lead compounds to target different receptor proteins that are involved in the onset of male infertility. A set of 210 plant phytochemicals were docked counter to active site residues of sex hormone-binding globulin, a disintegrin and metalloproteinase 17, and DNase I as receptor proteins. On the basis of binding scores and molecular dynamics simulation, the phytochemicals tricin, quercetin, malvidin, rhamnetin, isorhamnetin, gallic acid, kaempferol, esculin, robinetin, and okanin were found to be the potential drug candidates to treat male infertility. Molecular dynamics simulation showed tricin as a strong inhibitor of all selected receptor proteins because the ligand-protein complexes remained stabilized during the entire simulation time of 100 ns. Further, an in vivo study was designed to evaluate the effect of tricin in male rats with nicotine-induced infertility. It was explored that a high dose of tricin significantly reduced the levels of alanine transaminase, aspartate transaminase, urea, creatinine, cholesterol, triglyceride, and low-density lipoprotein and raised the level of high-density lipoprotein in intoxicated male rats. A high dose of tricin also increased the reproductive hormones (i.e., testosterone, luteinizing hormone, follicle-stimulating hormone, and prolactin) and reduced the level of DHEA-SO4. The phytochemical (tricin, 10 mg/kg body weight) also showed significant improvement in the histo-architecture after nicotine intoxication in rats. From the current study, it is concluded that the phytochemical tricin could serve as a potential drug candidate to cure male infertility.

RESUMO

Hantaviruses are enveloped negative (-) single-stranded RNA viruses belongs to Hantaviridae family, hosted by small rodents and entering into the human body through inhalation, causing haemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) also known as hantavirus cardiopulmonary syndrome (HCPS). Hantaviruses infect approximately more than 200 000 people annually all around the world and its mortality rate is about 35%-40%. Hantaviruses play significant role in affecting the target cells as these inhibit the apoptotic factor in these cells. These viruses impair the integrity of endothelial barrier due to an excessive innate immune response that is proposed to be central in the pathogenesis and is a hallmark of hantavirus disease. A wide range of different diagnostic tools including polymerase chain reaction (PCR), focus reduction neutralization test (FRNT), enzyme-linked immunosorbent assay (ELISA), immunoblot assay (IBA), immunofluorescence assay (IFA), and other molecular techniques are used as detection tools for hantavirus in the human body. Now the availability of therapeutic modalities is the major challenge to control this deadly virus because still no FDA approved drug or vaccine is available. Antiviral agents, DNA-based vaccines, polyclonal and monoclonal antibodies neutralized the viruses so these techniques are considered as the hope for the treatment of hantavirus disease. This review has been compiled to provide a comprehensive overview of hantaviruses disease, its pathophysiology, diagnostic tools and the treatment approaches to control the hantavirus infection.

RESUMO

The applications of exogenous hormones in different species for the induction of oocyte production, final oocyte maturation (FOM), and spawning for their reproduction is getting more attention day by day. The current preliminary research work was carried out to induce breeding in Clarias gariepinus, commonly known as African catfish, imported from Thailand. Single doses of two hormones as Ovaprim and human menopausal gonadotropin (hMG) were used and the research work was carried out at Muzaffargarh Fish Hatchery Punjab, Pakistan. A total of twenty-four (n = 24) C. gariepinus were selected having body weight approximately 2 kg and divided into two main groups based on gender as male (n = 12) and female (n = 12). For milt collection, all males were treated with Ovaprim 0.5 mg/kg body weight (b.w.) and female fish were divided into three groups as A, B, and C with four (n = 4) fish in each group. Group A was injected with only normal saline (control group) while fish in group B and group C were treated with hMG at 0.5 mg/kg b.w. and Ovaprim 0.5 mg/kg b.w., respectively. Then, after 6 h of hormone injections until 48 h, spawned eggs, eggs' weight, fertilization rate, hatching rate, survival rate, fecundity, and deformed larvae were investigated. The results revealed that Ovaprim injection significantly (p < 0.05) modulate the reproductive parameters in group C while no breeding was induced in both control and hMG-treated groups. Hence, it could be concluded that Ovaprim has the potential to induce breeding in African catfish, while in the current study, hMG failed to induce breeding. However, trials at large scales are required to further explore the effect of different doses of both tested hormones by increasing the treated subjects particularly in Pakistani fish farms.

RESUMO

Naegleria fowleri, a thermophilic flagellate amoeba known as a "brain-eating" amoeba, is the aetiological agent of a perilous and devastating waterborne disease known as primary amoebic meningoencephalitis (PAM), both in humans as well as in animals. PAM is a rare but fatal disease affecting young adults all around the world, particularly in the developed world but recently reported from developing countries, with 95%-99% mortality rate. Swimmers and divers are at high risk of PAM as the warm water is the most propitious environment adapted by N. fowleri to cause this infection. Infective amoeba in the trophozoite phase enter the victim's body through the nose, crossing the cribriform plate to reach the human brain and cause severe destruction of the central nervous system (CNS). The brain damage leads to brain haemorrhage and death occurs within 3-7 days in undiagnosed cases and maltreated cases. Though the exact pathogenesis of N. fowleri is still not known, it has exhibited two primary mechanisms, contact-independent (brain damage through different proteins) and contact-dependent (brain damage through surface structures food cups), that predominantly contribute to the pathogen invading the host CNS. For the management of this life-threatening infection different treatment regimens have been applied but still the survival rate is only 5% which is ascribed to its misdiagnosis, as the PAM symptoms closely resembled bacterial meningitis. The main objectives of this review article are to compile data to explore the sources and routes of N. fowleri infection, its association in causing PAM along with its pathophysiology; latest techniques used for accurate diagnosis, management options along with challenges for Pakistan to control this drastic disorder.

RESUMO

The advent of antibiotics revolutionized medical care resulting in significantly reduced mortality and morbidity caused by infectious diseases. However, excessive use of antibiotics has led to the development of antibiotic resistance and indeed, the incidence of multidrug-resistant pathogens is considered as a major disadvantage in medication strategy, which has led the scholar's attention towards innovative antibiotic sources in recent years. Medicinal plants contain a variety of secondary metabolites with a wide range of therapeutic potential against the resistant microbes. Therefore, the aim of this review is to explore the antibacterial potential of traditional herbal medicine against bacterial infections. More than 200 published research articles reporting the therapeutic potential of medicinal plants against drug-resistant microbial infections were searched using different databases such as Google Scholar, Science Direct, PubMed and the Directory of Open Access Journals (DOAJ), etc., with various keywords like medicinal plants having antibacterial activities, antimicrobial potentials, phytotherapy of bacterial infection, etc. Articles were selected related to the efficacious herbs easily available to local populations addressing common pathogens. Various plants such as Artocarpus communis, Rheum emodi, Gentiana lutea L., Cassia fistula L., Rosemarinus officinalis, Argemone maxicana L, Hydrastis canadensis, Citrus aurantifolia, Cymbopogon citrates, Carica papaya, Euphorbia hirta, etc, were found to have significant antibacterial activities. Although herbal preparations have promising potential in the treatment of multidrug-resistant bacterial infection, still more research is required to isolate phytoconstituents, their mechanism of action as well as to find their impacts on the human body.

RESUMO

Hepatitis C virus (HCV) is a primary cause of chronic liver disease along with various complications like liver cirrhosis and malignancy which leads to death. It has infected more than 185 million people worldwide. There is no congruence established for the treatment of various genotypes of HCV infection owing to diversity in prevalence globally. Assessment of affected individuals with HCV by polymerase chain reaction (PCR), viral load of HCV and liver enzyme levels (i.e., ALT and AST) are the foundation to evaluate the safety and efficacy of HCV therapies. The antiviral efficacy has been greatly improved and sustained viral response (SVR) rates increased from 6% with interferon monotherapy to 50-80% with PEG-interferon/ribavirin combination therapy to >95% after the approval of all interferon free oral direct acting antiviral agents. The main objective of this review article is to compile data from reference sources regarding the old and current therapeutic strategies used to manage HCV infection. It is accepted that chronic HCV infection increases patient's thrombocytopenia and neutropenia risk and complications increased in co-morbid disorders like in tuberculosis, HIV, diabetes etc. In past treatment associated side effects were the major consequences and many patients have to stop the treatment. But after the approval of direct acting antiviral drugs create a revolution in the treatment of HCV infection. So, it could be concluded that current combination therapies are a promising hope to eradicate and to control HCV but some safety concerns required more considerations Therefore, this review focus on the available latest combination therapies and their effectiveness to eradicate HCV infection.

RESUMO

The hexose monophosphate (HMP) shunt acts as an essential component of cellular metabolism in maintaining carbon homeostasis. The HMP shunt comprises two phases viz. oxidative and nonoxidative, which provide different intermediates for the synthesis of biomolecules like nucleotides, DNA, RNA, amino acids, and so forth; reducing molecules for anabolism and detoxifying the reactive oxygen species during oxidative stress. The HMP shunt is significantly important in the liver, adipose tissue, erythrocytes, adrenal glands, lactating mammary glands and testes. We have researched the articles related to the HMP pathway, its metabolites and disorders related to its metabolic abnormalities. The literature for this paper was taken typically from a personal database, the Cochrane database of systemic reviews, PubMed publications, biochemistry textbooks, and electronic journals uptil date on the hexose monophosphate shunt. The HMP shunt is a tightly controlled metabolic pathway, which is also interconnected with other metabolic pathways in the body like glycolysis, gluconeogenesis, and glucuronic acid depending upon the metabolic needs of the body and depending upon the biochemical demand. The HMP shunt plays a significant role in NADPH2 formation and in pentose sugars that are biosynthetic precursors of nucleic acids and amino acids. Cells can be protected from highly reactive oxygen species by NADPH 2 . Deficiency in the hexose monophosphate pathway is linked to numerous disorders. Furthermore, it was also reported that this metabolic pathway could act as a therapeutic target to treat different types of cancers, so treatments at the molecular level could be planned by limiting the synthesis of biomolecules required for proliferating cells provided by the HMP shunt, hence, more experiments still could be carried out to find additional discoveries.

RESUMO

The aim of this study is to review the efficacy of herbal and allopathic drugs used to manage and treat psoriasis. The review has been compiled using reference materials from major databases, Online Journals, Science Direct, Scopus, Open J Gate, Google Scholar and PubMed. Psoriasis is a common skin disease affecting 2-3% of the world's population. It is cosmetically debilitating and chronic disease, which occurs both in developing and developed countries. It can affect any part of the body, but the most common sites are the elbows, knees, and scalp. It is usually treated with synthetic medicine either given systematically or applied locally. The prescribed synthetic medicines used for the treatment of psoriasis are associated with severe side effects and complications, thus researchers around the world are trying to explore new, more effective, and safer drugs from natural resources. Medicinal plants are safe and efficacious, and most of the people all over the world rely on herbal medicine due to their easy availability, low cost, and efficacy for treating psoriasis. A number of medicinal plants having therapeutic potential with high efficacy are used in the treatment of psoriasis have been described. Moreover, studies should be conducted to isolate and investigate the mechanism of actions of phytochemicals responsible for anti-psoriasis potential.

RESUMO

Urinary tract infection (UTI) is one of the most severe public health problem affecting both sexes but females are more susceptible due to the differences in urogenital and reproductive anatomy, physiology and lifestyle. As in UTI, different parts of the urinary tract are affected and morbidity due to UTI is more common in women of all ages and older men. Due to multi-drug resistant strains and high recurrence rate, UTI has become a major socioeconomic burden. The current review article was aimed to describe the natural therapeutic strategies to manage and cure the UTI. For this purpose, different databases including Google Scholar, Cochrane database, and PubMed etc. were explored. Inclusion criteria were any research article investigating the current therapy of UTI. It was found that microbial infections including Escherichia coli, Enterococcus faecalis and Klebsiella species are the major causes of UTI with different signs and symptoms including painful urination or dysuria, hematuria, urinary urgency, burning micturition, frequent urination, nausea, and vomiting. Antibiotics like trimethoprim, sulfamethoxazole, quinolone etc. as the first choice of the drug are used worldwide. However, due to microbial resistance, several life-threatening side effects, repeated high doses, high cost and low efficacy of these antibiotics motivated the researchers to explore natural remedies for the treatment of UTI. Herbal medicines are effective to combat bacterial resistance with high efficacy, and easy availability with minimal or no side effects. For these reasons it has attained the attention of researchers wanting to explore the herbal treatment of UTI. Vaccinium macrocarpon, Tribulus terrestris, Trachyspermum copticum, Cinnamomum verum and Hybanthusenn easpermus are some common medicinal plants reported to have therapeutic potential for the management and cure of the UTI. Although herbal medicines have more potential over conventional medicine but more discoveries are required to explore the phytoconstituents and their mechanism of action responsible for the management and cure of UTI.

RESUMO

Human immunodeficiency virus (HIV) causes the potentially life-threatening and chronic disease called acquired immune deficiency syndrome (AIDS). The main target of this viral disease is to suppress the immune system and make the body unresponsive to external stimuli. According to global health observatory data since epidemic, more than 78 million people were affected by HIV and 39 million people died globally. Until 2017, 36.5 million people were living with HIV. An estimated 0.8% (0.6%-0.9%) of adults aged 15-49 years worldwide is living with HIV. The World Health Organization (WHO) reported that the African region remains most severely affected, with nearly one in every 25 adults (4.1%) living with HIV and accounting for nearly two-thirds of the people living with HIV worldwide. WHO reported that globally only 21.7 million (19.1 million-22.6 million) people have had access to antiretroviral therapy up to 2017. Currently, antiretroviral therapy (ART) is available for the control of HIV but has serious associated side effects such as lipodystrophy. Because of the limitations, associated with ART, researchers throughout the world are trying to explore and develop more reliable and safe drugs from natural resources to manage HIV infection. A wide range of medicinal plants have been studied and have reported significant potential against HIV. Plants like Rheum palmatum L., Rheum officinale, Trigonostem axyphophylloides, Vatica astrotricha, Vernonia amygdalina, Hypoxias pelargonium, Sidoides hemerocallidea and Sutherlandia frutescens etc. have high efficacy to cure HIV. The exact mechanism of action is still not known but various phytoconstituents isolated from medicinal plants such as alkaloids, flavonoids, polyphenols, terpenoids, tannins, proteins and coumarins have the potential to interrupt the life cycle of HIV as well as act as immunomodulators to enhance the immune system of infected patients with no well reported side effects. It could be concluded that medicinal plants have potential for the management of HIV/AIDS but more studies are needed to reveal rigorous efficacy and safety concerns by conducting clinical trials at vast level to explore therapeutic impact of medicinal plants.

RESUMO

Insomnia is a state defined as trouble with sleep; it is a chronically disabling condition and is now significantly prevalent, imposing enormous health and economic burdens both on individuals and on society. This state includes trouble in falling asleep, problems staying asleep, fragmented sleep (repeatedly awakening at night), and/or awakening before time in the morning. This difficulty in sleeping causes feeling exhausted during the day and trouble with daytime activities including driving, family responsibilities, and completion of valued daily routines. Different types of synthetic sedative drugs are used to handle nervous system changes, but repeated use of sedatives caused tolerance in the human body. After a while, people had to take a heavy dose of sedative to make them feel sleepy, which imposes extra toxic effects on vital organs of the body. Medicinal plants are gaining more and more attention as sedative agents because herbs contained different types of natural bioactive metabolites with not well reported side effects. In addition, medicinal plants have economic, high efficacy and are easy available. So in current review plants possessing sedative activities have been compiled with their constituents responsible to manage insomnia. Review of the literature indicated that medicinal plants from various systems of medicine have been reported to possess sedative activity. This review suggests that medicinal plants are efficacious for insomnia; further laboratory and clinical studies are required.

RESUMO

BACKGROUND: Herbal medicine plays an important role in health, particularly in remote parts of developing areas with few health facilities. According to WHO estimates, about three-quarters of the world's population currently use herbs or traditional medicines to treat various ailments, including liver diseases. Several studies have found that the use of medicinal plants was effective in the treatment of infectious and non-infectious diseases. Hepatitis and liver cirrhosis associated with many clinical manifestations can be treated with allopathic medicines, but reports of a number of side effects including immunosuppression, bone marrow suppression, and renal complications have motivated researchers to explore more natural herbal medicines with low or no side effects and with high efficacy in treating hepatic diseases. METHODS: Databases including PubMed, Medline, and Google Scholar were searched for findings on the hepatoprotective effects of plants. RESULTS: Various medicinal plants are used for the treatment of liver disorders. The range of alternative therapies is huge, and they are used worldwide, either as part of primary health care or in combination with conventional medicine. Hepatoprotective plants contain a variety of chemical constituents including flavonoids, alkaloids, glycosides, carotenoids, coumarins, phenols, essential oil, organic acids, monoterpenes, xanthenes, lignans, and lipids. CONCLUSION: This review shows that numerous plants are found to contain hepatoprotective compounds. However, further studies are needed to determine their association with existing regimes of antiviral medicines and to develop evidence-based alternative medicine to cure different kinds of liver disease in humans.

RESUMO

Malaria and typhoid fever are among the major infectious diseases which impose significant health and socioeconomic burden on affected populations. Further, co-infection and resembling symptomatology in both infections, mostly leads to misdiagnosis and mistreatment. So co-infection of malaria and typhoid fever is becoming a major issue in tropical and subtropical countries. The current study was planned to explore the rate of co-infection of malaria and typhoid fever to show the diagnostic challenges and people health implications in the local population of Faisalabad-Pakistan. For this purpose, 144 samples (n=144) were collected from suspected subjects both male (n=74) and female (n=70) (comprises of three age group ranges viz >01-10, 11-20 and above 20 years old) of typhoid fever and malaria from October to December 2017 at Children Hospital, Faisalabad-Pakistan. Thick smear as a gold standard technique for malaria diagnosis and Widal agglutination technique for typhoid diagnosis were used. Results revealed that the prevalence of co-infection in selected subjects was 6.3% (n=9) with higher prevalence in female subjects (7.1%) as compared to males (5.4%). Further, it was also reported that age groups >01-10 years old, 11-20 years old and 21-above years old have6.6 % (n=75), 5.7 % (n=35) and 5.8% (n=34), coinfection prevalence respectively. In the present study, it could be concluded that although the prevalence of co-infection of malaria and typhoid fever in the studied population was possible but sensitivity of diagnostic tools was limited, so more reliable, specific and sensitive diagnostic tools are required to report confidently more precise correlation of these infectious diseases.

RESUMO

Viral infections are being managed therapeutically through available antiviral regimens with unsatisfactory clinical outcomes. The refractory viral infections resistant to available antiviral drugs are alarming threats and a serious health concern. For viral hepatitis, the interferon and vaccine therapies solely are not ultimate solutions due to recurrence of hepatitis C virus. Owing to the growing incidences of viral infections and especially of resistant viral strains, the available therapeutic modalities need to be improved, complemented with the discovery of novel antiviral agents to combat refractory viral infections. It is widely accepted that medicinal plant heritage is nature gifted, precious, and fueled with the valuable resources for treatment of metabolic and infectious disorders. The aims of this review are to assemble the facts and to conclude the therapeutic potential of medicinal plants in the eradication and management of various viral diseases such as influenza, human immunodeficiency virus (HIV), herpes simplex virus (HSV), hepatitis, and coxsackievirus infections, which have been proven in diverse clinical studies. The articles, published in the English language since 1982 to 2017, were included from Web of Science, Cochrane Library, AMED, CISCOM, EMBASE, MEDLINE, Scopus, and PubMed by using relevant keywords including plants possessing antiviral activity, the antiviral effects of plants, and plants used in viral disorders. The scientific literature mainly focusing on plant extracts and herbal products with therapeutic efficacies against experimental models of influenza, HIV, HSV, hepatitis, and coxsackievirus were included in the study. Pure compounds possessing antiviral activity were excluded, and plants possessing activity against viruses other than viruses in inclusion criteria were excluded. Hundreds of plant extracts with antiviral effect were recognized. However, the data from only 36 families investigated through in vitro and in vivo studies met the inclusion criteria of this review. The inferences from scientific literature review, focusing on potential therapeutic consequences of medicinal plants on experimental models of HIV, HSV, influenza, hepatitis, and coxsackievirus have ascertained the curative antiviral potential of plants. Fifty-four medicinal plants belonging to 36 different families having antiviral potential were documented. Out of 54 plants, 27 individually belong to particular plant families. On the basis of the work of several independent research groups, the therapeutic potential of medicinal plants against listed common viral diseases in the region has been proclaimed. In this context, the herbal formulations as alternative medicine may contribute to the eradication of complicated viral infection significantly. The current review consolidates the data of the various medicinal plants, those are Sambucus nigra, Caesalpinia pulcherrima, and Hypericum connatum, holding promising specific antiviral activities scientifically proven through studies on experimental animal models. Consequently, the original research addressing the development of novel nutraceuticals based on listed medicinal plants is highly recommended for the management of viral disorders.

RESUMO

In diabetic patients, electrolyte disorders frequently occur with the characteristic changes in minerals like calcium and magnesium etc. Several medicines are used to manage diabetes mellitus but they exert adverse effects. Plants are a valuable alternative to synthetic medicines because they are easily available, economical and have fewer side effects. Ipomoea batatas L is a well-known antidiabetic plant (sweet potato) but its effects on calcium and magnesium concentration have not studied. The prime focus of this study is to estimate the potential of Ipomoea batatas L peel-off on magnesium and calcium level in Alloxan-induced diabetic rats. Alloxan monohydrate was mixed in 0.9% NaCl solution and administrated [150 mg/kg (S/C)] to male Wistar rats to induce diabetes. After three days blood samples were collected and blood glucose level was recorded. Wistar rats having a blood glucose level of 200 mg/dl and above were selected for the study. Methanol and water extract of Ipomoea batatas L peel-off was given orally with a dose rate of 4g/day. Calcium and magnesium estimation was done using an atomic absorption spectrophotometer. Our results revealed an increase in both the calcium and magnesium level in heart, brain, liver, hind limb, and forelimb after Ipomoea batatas extract treatment. In kidneys decreased calcium level was noted as they excrete calcium. Mineral (Calcium, magnesium) level was increased in all organs except kidney after both extracts treatment. Ipomoea batatas being anti-diabetic in nature also maintain the homeostasis of calcium and magnesium in diabetes. Therefore, we propose the long-term use of such agents might help in the prevention of diabetes-associated complications. However, the validation of these results to human population needs further extensive study.

RESUMO

The potent phytotherapeutic modalities against the hepatotoxicity have motivated us to explore numerous plants and polyherbal preparations because conventional drug discovery is more expensive and tedious. So, this study was conducted to evaluate the hepatoprotective potential of a polyherbal formulation (PHF), comprising of Solanum nigrum, Silybum marianum, Atrmesia absinthium, Achillea millifolium and Cichorium intybus against carbon tetrachloride(CCl4) induced hepatotoxicity in experimental rats. CCl4intoxicationinduced vacuole formation and fastdegeneration so selective liver enzymes including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alkalinephosphatase (ALP) and total bilirubin in rat's plasma,as well as liver histological architecture, were used to evaluate the effect of herbal treatments with different doses (ranging 100-500 mg/kg) for two weeks. Statistical analysis showed that PHF significantly (P<.05) improved the level of liver enzymes as well as improve the liver architecture comparative to control groups. It could be concluded from current findings that PHF prepared from Solanum nigrum, Silybum marianum, Atrmesia absinthium, Achillea millifiloium and Cichorium intybus have some hepatoprotective activities.

RESUMO

Diabetes is a metabolic disorder characterized by chronic hyperglycemia and associated with dysfunction and failure of various body organs. Alarming increase in prevalence rate has made this disorder a major health problem globally. The available treatment modalities are not sufficient to combat diabetes and associated complications. A number of medicinal plants have a significant antidiabetic potential against diabetes mellitus. We have listed the use of important medicinal herbs for the treatment and management of diabetes in this review.

RESUMO

Diabetes causes elevated blood sugar levels, and it has been categorized as one of the most frequent causes of death worldwide. This work aimed to analyze and compare the nutraceutical and therapeutic efficacy of fenugreek seeds (FSs) (Trigonella foenum-graecum) and black cumin seeds (BCSs) (Nigella sativa) against streptozotocin-induced diabetes mellitus in albino rats. FS and BCSs were evaluated for proximate analysis, phytochemicals, and antioxidant activities. Male albino rats were used to evaluate the in vivo antidiabetic activities of these medicinal plants for 42 days. Blood samples were drawn at regular intervals of 1 week to analyze blood glucose, plasma insulin, and cholesterol levels and to determine the homeostatic model assessment of insulin resistance (HOMA IR) index. At the end of the trial, pancreas tissue was also collected for histological examination. Results of the proximate analysis showed the significant presence of moisture, ash, fat, protein, and fiber. Antioxidant parameters like 2,2-diphenyl-1-picrylhydrazyl, total phenolic content, and total flavonoid content were found to be significant. There was a significant (p < 0.05) decrease in blood glucose level, serum cholesterol level, and insulin resistance in treatment groups T3-T5. Insulin and body weight results of treatment groups were significant (p < 0.05) compared to streptozotocin-intoxicated animals. Histological examination revealed the nutraceutical impact of selected herbal plants due to enhancing impact on the size and the number of ß-cells in the pancreas. Findings of current research work explore the antidiabetic capacity of selected nutraceutical and medicinal plants.

RESUMO

The use of traditional medicines has tremendously increased over the past few decades. Approximately 80% of the world's population relies on traditional medicines for their primary healthcare needs because of their cost effectiveness and efficiency with no or minimal side effects. Zootherapy refers to the use of medicines that are prepared or derived from animals or from their products. The current study documented the folk knowledge related to the practice of various animal-derived products and ethnozoological based drugs used as medicines by the residents of the Cholistan desert of Bahawalpur (Pakistan). In this regard 46 knowledgeable and reliable elderly people, hakims and spiritual healers ranging from 35-60 years of age having knowledge related to zootherapy were included in the current study. A field survey from February 2006 to November 2007 was conducted by interviewing the selected respondents through a structured questionnaire. They provided knowledge regarding the use of animals and their derived products in traditional medicine. The zootherapeutic knowledge was based on both domestic animals as well as wild animals. A total of 20 animal species were included in the study, among which nine animals were domestic while 11 were wild animals. Among selected animals, nine were mammals, four birds, four reptiles and three insects. It was reported that camel was the most commonly used (n = 32 respondents) among mammals while Pigeon (n = 39 respondents), Spiny-tailed lizard (n = 41 respondents) and Indian honey bee (n = 27 respondents) among birds, reptiles and insects, respectively, have significant use for the treatment of different diseases. Based on this communication we could recommend that this type of abandoned knowledge should be considered for the management and conservation of faunistic resources. However, the advantageous role of animals and their products was reported but more extensive research is required to explore the bioactive constituents in the raw material of these animals responsible for their beneficial effects.

RESUMO

BACKGROUND: Thalassemia is a hereditary hemolytic anemia marked by a defect in synthesizing one or more globin chains in hemoglobin. In Pakistan, approximately 10,000 patients with thalassemia are primarily dependent on blood transfusions. The ß-thalassemia patients require blood transfusions and iron chelation therapy. Patients who need blood transfusions are at an increased risk of contracting transfusion-transmitted infections (TTIs) such as hepatitis B and C viruses (HBV and HCV, respectively), as well as the human immunodeficiency virus (HIV). OBJECTIVE: This systemic review aims to assess the prevalence of TTIs in transfusion-dependent ß-thalassemia patients in Asia. METHODS: The data for the systematic review were gathered from PubMed, Google Scholar, the Directory of Open Access Journals (DOAJ), and ScienceDirect using the following keywords: "prevalence, HBV, HCV, HIV, thalassemia, and transfusion-transmitted infections (TTIs)," and so on. This review includes the research articles that address the prevalence of viral infections in thalassemic patients following blood transfusion. RESULTS: A preliminary search of various databases identified 231 potential studies. 157 duplicate studies were eliminated, and the eligibility of 59 full-length articles was determined. Only 43 studies met the inclusion criteria. Among the 43 studies analyzed, 11 reported a high prevalence of HCV alone in thalassemic patients, while 21 reported a high prevalence of HCV and HBV infection in thalassemic patients. Eight studies reported the prevalence of all three TTIs examined, namely, HCV, HBV, and HIV, in patients with transfusion-dependent thalassemia. CONCLUSION: Preventable transfusion-transmitted infections occur frequently, and robust national policies and hemovigilance are required to detect and mitigate the infection risk.
