RESUMO

In the present study, the beneficial effect of leaves of Ziziphus mauritiana on testosterone, estradiol, progesterone, LH hormones, blood glucose, and total cholesterol levels in the experimentally induced polycystic ovaries of female Sprague Dawley rats were evaluated. Letrozole was used to induce PCOS in rats, and clomiphene citrate was used as a standard control. This study was carried out in vivo on 30 female rats where group I received normal saline and group II to V were treated with letrozole (1 mg/kg/day), which was dissolved in normal saline orally for 21 days to induce PCOS. After PCOS induction, test groups III and IV were orally treated with ZMME at a dose of 100 mg/kg and 200 mg/kg for 14 days, respectively, and group V was treated with clomiphene citrate (2 mg/kg) orally for 14 days. At the end of the experimental period, the animals were sacrificed by cervical dislocation, and blood samples were collected by cardiac puncture. After blood collection, the ovaries were removed and weighed. The results showed that Ziziphus mauritiana normalized all hormones and total cholesterol levels. The HPTLC profile showed the presence of gallic acid, rutin, quercetin, and ursolic acid. Many studies have reported that quercetin is effective against PCOS and its complications; it suppresses insulin resistance and reduces testosterone and LH levels. The present study showed an improvement in the inflammatory microenvironment of the ovarian tissue in the PCOS rat model. This research concluded that the leaves of Ziziphus mauritiana have potential efficacy in the treatment of PCOS by normalizing abnormal hormones and total cholesterol levels, which could be due to the presence of quercetin in the leaves.

RESUMO

Traditional medicine claims that various components of the Phoenix dactylifera (date plant) can be used to treat memory loss, fever, inflammation, loss of consciousness, and nerve disorders. The present study aims to evaluate the effectiveness of Phoenix dactylifera fruit extracts (PDF) against rat sickness behaviour caused by lipopolysaccharide (LPS) by assessing behavioural and biochemical parameters. PDF was prepared by extracting dry fruits of P. dactylifera with a methanol:water (4:1, v/v) mixture. The PDF was evaluated for phenolic and flavonoid content and HPLC analysis of quercetin estimation. Adult Wistar rats were treated with LPS, PDF + LPS and dexamethasone + LPS. Water and food intake, behavioural tests such as locomotor activity, tail suspension and forced swim tests were conducted. Furthermore, alanine transaminase (ALT) and aspartate transaminase (AST) were estimated in plasma and malondialdehyde (MDA), reduced glutathione (GSH), nitrite, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), were estimated in the brain. PDF ameliorated LPS-induced sickness behaviour by reducing MDA, nitrite, IL-6, and TNF-α levels and improving GSH, behavioural alteration, water and food intake in the treated rats. In the plasma of the treated rats, PDF also decreased the levels of ALT and AST. The outcomes demonstrated the efficacy of PDF in reducing the sickness behaviour caused by LPS in rats. The authors believe that this study will provide the groundwork for future research to better understand the underlying mechanisms of action and therapeutic efficacy.

RESUMO

The host's response to acute infections or tissue injury is a sophisticated and coordinated adaptive modification called sickness behaviour. Many herbs have been studied for their ability to protect animals against experimentally induced sickness behaviour. However, there is a lack of knowledge and experimental evidence on the use of herbal bioactive compounds (HBACs) in the management of sick behaviour. The goal of this review is to provide a concise summary of the protective benefits and putative mechanisms of action of phytochemicals on the reduction of lipopolysaccharide (LPS)-induced sickness behaviour. Relevant studies were gathered from the search engines Scopus, ScienceDirect, PubMed, Google Scholar, and other scientific databases (between 2000 and to date). The keywords used for the search included "Lipopolysaccharide" OR "LPS" OR "Sickness behaviour" OR "Sickness" AND "Bioactive compounds" OR "Herbal medicine" OR "Herbal drug" OR "Natural products" OR "Isolated compounds". A total of 41 published articles that represented data on the effect of HBACs in LPS-induced sickness behaviour were reviewed and summarised systemically. There were 33 studies that were conducted in mice and 8 studies in rats. A total of 34 HBACs have had their effects against LPS-induced changes in behaviour and biochemistry investigated. In this review, we examined 34 herbal bioactive components that have been tested in animal models to see if they can fight LPS-induced sickness behaviour. Future research should concentrate on the efficacy, safety, and dosage needed to protect against illness behaviour in humans, because there is a critical shortage of data in this area.

RESUMO

BACKGROUND: The substantial and increasing use of medications escalating the risk of harm globally. The serious medication errors in hospital and community settings resulting from patient injury and death. Hence, a cross-sectional study was aimed to analyse the prescribing and dispensing errors in the outpatient departments of a south Indian hospital. MATERIALS AND METHODS: A prospective cross-sectional study was carried out to evaluate the prescribing, and dispensing errors in outpatients who seek patient counseling at the tertiary care multispecialty hospital. The data were collected from various sources such as patient's prescriptions and dispensing records from the pharmacy. RESULTS: A total of 500 prescriptions were screened and identified 65.60% of prescriptions with at least any one type of medication errors. Out of 328 prescriptions, 96.04% were handwritten and 3.96% were computerised prescriptions. Among the 328 prescriptions with medication errors, 32.62% noticed prescribing errors, 37.80% with dispensing errors, and 29.58% with both prescribing and dispensing errors. Out of these 328 prescriptions, 74.09% prescriptions were found to have polypharmacy. DISCUSSION: Medication errors are serious problems in healthcare and can be a source of significant morbidity and mortality in healthcare settings. The present study showed that dispensing errors were the most common among the types of medication errors, in these particularly wrong directions were the most common types of errors. CONCLUSION: This study concludes that the overall prevalence of medication errors was around 80%, but there were no life-threatening events observed. A clinical pharmacist can play a major role in this situation appears to be a strong intervention and early detection and prevention of medication errors and thus can improve the quality of care to the patients.

RESUMO

BACKGROUND: Resistance to antibiotics causes negative impact on health of the patients. Antibiotic resistance is the major global concern that has to be nullified for the better health outcome. The knowledge on antibiotics is very essential for the students who undertake pharmacy and health science courses. Hence a study was aimed to assess the level of knowledge, attitude, perception and practice on antibiotics usage among the pharmacy students of King Khalid University, KSA. MATERIALS AND METHODS: A prospective online questionnaire based survey was carried out among the pharmacy students about knowledge, attitude perception and practice of antibiotics using 5-point "Likert scale" and true/false responses. The responses range from strongly agree to strongly disagree, and always to never were recorded. The data were analysed by using simple descriptive statistics. RESULTS: Out of 300 students approached 212 responded and the response rate was found to be 71%. In this study, most (95%) of the students were aware of the emerging problem of antibiotic resistance due to inappropriate use of antibiotics. Majority (89%) of the students agreed the inappropriate use of antibiotics can increase the overall cost of treatment. However, over half of the (54%) students were not aware of the antibiotic resistance that may be a nation-wide problem of Kingdom of Saudi Arabia. The net positive response (NPR) and net other response (NOR) of all items in perception on antibiotics received more or less equal responses. CONCLUSION: The knowledge of antibiotics usage among the students are considerably good compared with previous studies. However, the attitude, perception and practice on antibiotics usage among the pharmacy students are very poor. It alarms the need of appropriate education to enlighten antibiotic awareness for the better disease prevention and health outcomes for the benefit of patient community.
