Advanced photocatalysis as a viable and sustainable wastewater treatment process: A comprehensive review.

In our era, water pollution not only poses a serious threat to human, animal, and biotic life but also causes serious damage to infrastructure and the ecosystem. A set of physical, chemical, and biological technologies have been exploited to decontaminate and/or disinfect water pollutants, toxins, microbes, and contaminants, but none of these could be ranked as sustainable and scalable wastewater technology. The photocatalytic process can harmonize the sunlight to degrade certain toxins, chemicals, microbes, and antibiotics, present in water. For example, transition metal oxides (ZnO, SnO2, TiO2, etc.), when integrated into an organic framework of graphene or nitrides, can bring about more than 90% removal of dyes, microbial load, pesticides, and antibiotics. Similarly, a modified network of graphitic carbon nitride can completely decontaminate petrochemicals. The present review will primarily highlight the mechanistic aspects for the removal and/or degradation of highly concerned contaminants, factors affecting photocatalysis, engineering designs of photoreactors, and pros and cons of various wastewater treatment technologies already in practice. The photocatalytic reactor can be a more viable and sustainable wastewater treatment opportunity. We hope the researcher will find a handful of information regarding the advanced oxidation process accomplished via photocatalysis and the benefits associated with the photocatalytic-type degradation of water pollutants and contaminants.

A dispersive liquid-liquid microextraction followed by reverse-phase high-performance liquid chromatography for QuEChERS determination of chlorogenic acid.

INTRODUCTION: The presence of chlorogenic acid (CGA) not only imparts a characteristic flavour to foods but also makes them useful against chronic diseases and metabolic syndromes, especially diabetes mellitus and asthma. OBJECTIVES: The present study was designed to develop a quick, easy, cheap, effective, rugged, and safe (QuEChERS) and pragmatic method to analyse CGA in plant-based products by applying dispersive liquid-liquid microextraction (DLLME) followed by reverse-phase high-performance liquid chromatography under a diode array detector (RP-HPLC-DAD). METHODOLOGY: The DLLME was carried out using Triton X-100 as a dispersant and ethanol as an extraction solvent, while method development and validation activities were performed on a Shimadzu 10-AT HPLC-DAD system equipped with C-18 columns as stationary phases. RESULTS: The well-resolved peak for the standard CGA was observed at 2.92 min for the mobile phase comprising 0.1% aqueous formic acid-ethanol (22:78 v/v) of pH 3.0 programmed under an isocratic flow rate of 1.0 mL/min. The developed method was found to be linear (R2 = 0.9976) over 1-500 µg/mL of CGA concentration at 328 nm. Moreover, the assay was found to be repeatable with RSD ≤ 5.0, and the limit of detection (LOD) and limit of quantification (LOQ) were 0.0281 and 0.0853 µg/mL of CGA, respectively. The DLLME offered an overall recovery rate between 97.60% and 99.54% at an acceptable level of reproducibility [relative standard deviation (RSD) ≤ 5.0]. CONCLUSION: The developed assay was found to be a QuEChERS and pragmatic choice for the high-throughput analysis of CGA in plant-based products/foods. Finally, the analysis revealed the presence of an ample level of CGA in guava fruit in addition to coffee beans and black tea.

Centratherum anthelminticum seeds administration improved risk factor markers in metformin treated type 2 diabetic patients.

This study was designed to assess the effect of Centratherum anthelminticum seeds administration on blood and serum risk factor markers in type 2 diabetic (T2D) patients using metformin. It was a randomized non-blinded, controlled, 3month trial. T2D patients were registered from Sindh Government Hospital New Karachi, Karachi. There were 3 groups, DT (Diabetic Test, n=20), DC (Diabetic Control, n=20) HC (Healthy Control n=20, healthy individuals of similar age were selected). DC (metformin 500mg), DT (capsule of C. anthelminticum seeds powder CAPca + metformin 500mg each) and HC (CAPca 500mg) were given daily. Fasting blood glucose, body weights were monitored weekly while blood samples were collected on first and final day of the trial for biochemistry. Administration of CAPca showed significant decrease in % glycaemia (p<0.0001) and % Hb glycosylation (p<0.05) values. Serum risk factor markers including direct bilirubin & uric acid (p<0.01), creatine kinase & alanine aminotransferase (p<0.0001) and creatinine (p<0.05) were reduced significantly. CAPca administration improved blood and serum markers in healthy volunteers too. These improved blood & serum markers in T2D patients indorsed synergistic effect of CAPca with metformin to manage secondary challenges of T2D.

Deep Eutectic Liquids as Tailorable Extraction Solvents: A Review of Opportunities and Challenges.

Deep Eutectic Liquids (DELs) fall among the rapidly evolving discoveries of the 21st century, and these liquids are considered as alternative solvents to toxic and volatile organic liquids. Nevertheless, the emerging trend regarding the use of DELs in every field of physical and biological sciences, a lot of ambiguities and misconceptions exist about their formation, mechanism, and efficiencies observed or projected. A review of available technical data makes it obvious that these liquids have the potential to revolutionize the underdeveloped areas of analytical chemistry particularly the extraction/enrichment of analytes. To ensure the green and sustainable use of DELs, the researchers need to have a thorough understanding of DELs, their classification, chemistry, the nature and strength of molecular entanglements, and their tailorable features. Many researchers have declared these liquids recyclable but more attentive trials are needed to develop an authentic and straightforward DELs recycling methodology. The present review covers sound background knowledge and expert opinions about the technical definition of DELs, their classification, formation, recyclability, and tailorable features for their application as extraction solvent/sorbent in analytical chemistry.

Glycemic control and antioxidant potential of distinct fractions of camelus dromedaries fresh milk in streptozocin induced diabetic rats.

To analyze the antiglycemic effects and to evaluate the anti-oxidant levels in pre and post-camel milk fractions treated albino diabetic rats, sixty male Swiss albino rats weighing 30-40gm aged 2 to 3 months were randomly divided into six groups, A, B, C, D, E & F, each comprised of 10 animals. as Group A: Normal control, Group B: Streptozocin induced Diabetic group while Groups C, D, E & F were diabetic groups treated with various fractions of camel milk. Noteworthy alteration in blood glucose and antioxidant activity was observed between disease control (group B) and all the treated groups with a percentage decrease of about 25%, 12.98%, 11.57% and 10.17% in blood sugar in groups C, D, E and F respectively. Changes in total antioxidant capacity were significant with the rise of 92.30%, 30.76%, 46.15% and 38.46% respectively in groups C, D, E and F. Percentage difference in superoxide dismutase between group B and Group C of 85% was highest as compared to 45.90 %, 52.45% and 39.34% for groups D, E and F. Group C also showed a significantly higher increase in serum copper, zinc and Vitamin C. It is inferred that Camel milk has significant antiglycemic and antioxidant potential and may prove good complementary therapeutics for diabetes.

Analysis of dose and duration dependent effects of Allium sativum Linn and other hypocholesterolemic agents exhibited on dyslipidemia in patients with essential hypertension.

Globally, cardiovascular diseases (CVD) are one of the most significant cause of organ failure, mortality and substantial escalation of health care cost. Dyslipidemia and hypertension poses significant risks in cardiovascular diseases and morbidity and mortality can be minimized by altering risks factors. Dyslipidemia is one of the major leading cause of rise of global incidences and socioeconomic burden which necessitates to explore the pharmacological options of significant antilipemic activity with minimal untoward effects at affordable price. Allium Sativum (Garlic) proved medicinally effective in different clinical trials, but further investigations are required to investigate its effects on diabetes, hypertension and dyslipidemia based on variable doses and duration. In this study dose and duration dependent effects of Garlic were evaluated on hypertensive patients with dyslipidemia. Study was randomized, single blind and placebo controlled. Effects of tablets of garlic (KWAI) 300 mg in doses of daily 0.3g, 0.6g, 0.9g, 1.2g and 1.5g for 24 weeks were compared in humans. Each tablet contains 1.3 percent of alliin and 0.6 % of allicin. Results showed remarkable improvements in different serum lipid levels (Cholesterol, Triglycerides, Low density lipoproteins and High density lipoproteins) based on different doses and duration as compared to placebo and standard Lipid-lowering agent simvastatin.

Chemical Fingerprinting, Antioxidant, and Anti-Inflammatory Potential of Hydroethanolic Extract of Trigonella foenum-graecum.

In the current study, the antioxidant and anti-inflammatory potential of hydroethanolic extract of T. foenum-graecum seeds was evaluated. Phenolic profiling of T. foenum-graecum was conducted through high-performance liquid chromatography-photodiode array (HPLC-PDA) as well as through the mass spectrometry technique to characterize compounds responsible for bioactivity, which confirmed almost 18 compounds, 13 of which were quantified through a chromatographic assay. In vitro antioxidant analysis of the extract exhibited substantial antioxidant activities with the lowest IC50 value of both DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid) inhibition assays. The extract was found to be non-toxic against human RBCs and murine macrophage RAW 264.7 cells. Moreover, the extract significantly (p < 0.001) reduced the lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-α), intrlukin-6 (IL-6), prostaglandin E2 (PGE2), and nitric oxide (NO) in RAW 264.7 cells in a concentration-dependent manner. The hydroethanolic extract of T. foenum-graecum exhibited considerable anti-inflammatory potential by decreasing the cellular infiltration to the inflammatory site in both carrageenan-induced peritonitis and an air pouch model of inflammation. Pretreatment with T. foenum-graecum extract caused significant improvement in antioxidants such as superoxide dismutase (SOD), CAT (catalase), malondialdehyde (MDA), and myeloperoxidase (MPO) against oxidative stress induced by carrageenan. Based on our results of in vivo and in vitro experimentation, we concluded that hydroethanolic extract of T. foenum-graecum is a potential source of phenolic compounds with antioxidant and anti-inflammatory potential.

Association of Maternal Observation and Motivation (MOM) Program with m-Health Support on Maternal and Newborn Health.

Maternal and child nutrition has been a critical component of health, sustainable development, and progress in low- and middle-income countries (LMIC). While a decrement in maternal mortality is an important indicator, simply surviving pregnancy and childbirth does not imply better maternal health. One of the fundamental obligations of nations under international human rights law is to enable women to endure pregnancy and delivery as an aspect of their enjoyment of reproductive and sexual health and rights and to live a dignified life. The aim of this study was to discover the correlation between the Maternal Observation and Motivation (MOM) program and m-Health support for maternal and newborn health. A comparative study was done among 196 pregnant mothers (study group-94; control group-102 mothers) with not less than 20 weeks of gestation. Maternal outcomes such as Hb and weight gain and newborn results such as birth weight and crown-heel length were obtained at baseline and at 28 and 36 weeks of gestation. Other secondary data collected were abortion, stillbirth, low birth weight, major congenital malformations, twin or triplet pregnancies, physical activity, and maternal well-being. The MOM intervention included initial face-to-face education, three in-person visits, and eight virtual health coaching sessions via WhatsApp. The baseline data on Hb of the mothers show that 31 (32.98%) vs. 27 (28.72%) mothers in the study and control group, respectively, had anemia, which improved to 27.66% and 14.98% among study group mothers at 28 and 36 weeks of gestation (p < 0.001). The weight gain (p < 0.001), level of physical activity (p < 0.001), and maternal well-being (p < 0.01) also had significant differences after the intervention. Even after controlling for potentially confounding variables, the maternal food practices regression model revealed that birth weight was directly correlated with the consumption of milk (p < 0.001), fruits (p < 0.01), and green vegetables (p < 0.05). As per the physical activity and maternal well-being regression model, the birth weight and crown-heel length were strongly related with the physical activity and maternal well-being of mothers at 36 weeks of gestation (p < 0.05). Combining the MOM intervention with standard antenatal care is a safe and effective way to improve maternal welfare while upholding pregnant mothers' human rights.

Social Support, Self-Care Behaviour and Self-Efficacy in Patients with Type 2 Diabetes during the COVID-19 Pandemic: A Cross-Sectional Study.

Diabetes mellitus is a major public health issue that considerably impacts mortality, morbidity, and healthcare costs worldwide. The COVID-19 pandemic has created havoc in diabetes management, too, like other spectrums of life. A descriptive, cross-sectional study was adopted to determine the effect of Social Support, Self-Care Behaviour and Self-Efficacy in Type 2 Diabetes Mellitus (T2D) during this COVID-19 pandemic. Two hundred T2D patients who satisfied the inclusion criteria were chosen using a convenient sampling procedure. The tool consists of four sections, including socio-demographic characteristics, Multidimensional Scale of Perceived Social Support (MSPSS), revised Summary of Diabetes Self-Care Activities (SDSCA) Scale and modified Diabetes Management Self-Efficacy Scale (DMS). Descriptive and inferential statistics were used to analyze the obtained data. The mean and SD of diabetic management self-efficacy is 5.74 (1.95) and 4.37 (1.4), respectively, for patients with HbA1c < 6.5% and HbA1c ≥ 6.5%. The self-care activities of the patients who had good glycemic control were 4.31 (2.06) compared to 3.50 (1.73) who did not. The social support received by the patients was 6.13 (2.13) vs. 5.31 (1.67) among patients with glycemic control vs. no control. The results show that social support (p = 0.04), self-efficacy (p =0.01) and self-care activities (p = 0.001) were significantly related to the level of glycemic control of the T2D patients. A significant relationship was also identified between gender (p = 0.036), age (p = 0.001) and education status (p = 0.000) with HbA1c control of the participants. This study demonstrates a significant relationship between social support, self-care behaviours, self-efficacy and glycemic management in T2D patients. During this COVID-19 pandemic, interventions to enhance the self-care activities like exercise and social support to boost their self-efficacy; for better diabetes management, reducing diabetes complications or prolonging their onset are the need of the hour.

Design, DFT studies, antimicrobial and antioxidant potential of Binuclear N-heterocyclic Carbene (NHCs) complexes, Probing the aspect of DNA interaction through In-vitro and In-silico approach.

N-heterocyclic carbene (NHC) adducts have shown remarkable biological potential for numerous medical applications. With an aim to improve biological potential of benzimidazolium salts, newer analogues of benzimidazole and their silver complexes were synthesized and characterized. Synthesized salts (L1-L2) and silver complexes (C1-C2) were confirmed through elemental analysis, UV-visible spectroscopy, FTIR, 1H NMR & 13C NMR spectroscopy. The compounds C1 & C2 were found stable in solution form for studied time period when examined spectroscopically and showed optimum lipophilicity when measured for their partition coefficient through flask shake method. Synthesized compounds showed good antimicrobial potential against gram positive bacterial strain S. Aureus with IC50 2.02±0.12 and 2.11±0.13 µM respectively while 2.11±0.1 and 2.28±0.17 µM against gram negative bacterial strain E. Coli for C1 and C2 respectively. The interaction study of the related compounds with DNA was predicted by molecular docking study, which confirmed that the studied compound C1 (-8.04 kcal/mol) has a higher binding energy than compound C2 (-4.23 kcal/mol); Also, the compound C1 exhibits a better affinity against to DNA than Ethidium bromide (-7.68 kcal/mol) and cisplatin (-6.21 kcal/mol).The claim was practically assured through spectroscopic and viscometeric method which confirmed that compounds have good affinity for DNA with binding constant kb, 5.78×104 M-1 and 6.84×104 M-1 for C1 and C2 respectively.

Maceration-Mediated Liquid-Liquid Extraction and Reverse-Phase High-Performance Liquid Chromatography-Based Pragmatic Analysis of Silybins.

This study presents a pragmatic and easily scalable maceration-mediated liquid-liquid extraction (MMLLE) and reverse-phase high-performance liquid chromatography (RP-HPLC)-based determination of Silybins from plant material (Curcuma longa L.). The processing of calibration standards revealed that the RP-HPLC method was linear over a concentration range of 1-100 µg/mL with regression coefficient (R2) > 0.9950, limit of detection 0.02 µg/mL and limit of quantification <0.07 µg/mL. The optimum chromatographic conditions resolved Silybin A, Silybin B, Isosilybin A and Isosilybin B within 5 min of analysis time. The reproducible recovery rates of spiked flavonolignans (96.24-115.40%) from quality controls established the effectiveness of MMLLE procedure prior to HPLC determination. The real-time analysis revealed the presence of silybins in C. longa roots. The results further endorse that MMLLE prior to chromatographic determination may provide a more pragmatic analytical solution for the analysis/isolation of silybins.

Survivability Modeling and Resource Planning for Self-Repairing Reconfigurable Device Fabrics.

A resilient system design problem is formulated as the quantification of uncommitted reconfigurable resources required for a system of components to survive its lifetime within mission availability specifications. We show that this survivability metric can be calculated according to the residual functionality obtained from pools of dynamically configurable elements constituting the amorphous resource pool (ARP). The ARP is depleted based on the failure rate to replenish the functionality lost in a reconfigurable fabric due to the occurrence of permanent faults during the mission lifetime. While genetic algorithms are selected for the reparation method, any probabilistic or deterministic active repair strategy is covered without loss of generality. Parameters of this model are correlated with reliability specifications of Xilinx Virtex-4 field programmable gate array devices, which are then utilized for MCNC benchmark circuits along with a realistic space mission. Calculation of the spare fabric resources which must be budgeted for a mission, maximum mission lifetime, and repair policy parameters are realized using the proposed probabilistic survivability model for soft computing-based repair strategies.

Variation in biochemical and antioxidant attributes of Raphanus sativus in response to foliar application of plant leaf extracts as plant growth regulator.

The present study was aimed to appraise the variations in biochemical, antioxidant and nutritional attributes of radish (Raphanus sativus L.) under foliar application of plant leaf aqueous extracts i.e., mulberry leaf extract (MLE), brassica leaf extract (BLE), sorghum leaf extract (SLE) and moringa leaf extract (MoLE) as natural growth regulators. Samples were collected after three sprays of extracts and analyzed. Total phenolic constituents were determined using Folin-Ciocalteu reagent method, whereas antioxidant potential was evaluated by 1,1 diphenyl-2-picrylhydrazyl radical radical scavenging and reducing power assays. Results revealed that application of MLE, BLE, SLE, and MoLE not only improved growth, but also enhanced biochemical and antioxidant activities. Foliar spray of MoLE furnished relatively three folds higher amounts of extractable bioactive compounds (37.65 ± 0.94%), phenolic constituents (54.51-182.71 mg GAE/g f.w). The radical scavenging capacity (RSC) and reducing potential were also enhanced considerably. Furthermore, the moisture, dietary fiber, crude protein, and carotenoids were also enhanced in response of foliar spray of plant extracts. From results, it is concluded that plant extracts are effective sources of natural growth regulars and might be useful for the production of vegetables with improved nutritional value and antioxidant activity.

Effects of Allium sativum (garlic) on systolic and diastolic blood pressure in patients with essential hypertension.

The present study evaluated the effects of garlic on blood pressure in patients with essential hypertension. Patients (n=210) with stage 1 essential hypertension were divided into 7 groups named as A, B, C, D, E, F and G. Each group comprised of 30 patients. Each patient in group A, B, C, D and E has received garlic tablets at the dose of 300/mg. 600/mg, 900/mg, 1200/mg and 1500/mg in divided doses per day respectively for 24 weeks while Group F & group G were given tablet atenolol and placebo respectively. Blood pressure readings were recorded at weeks 0, 12 and 24. Present study showed significant decrease in both Systolic and Diastolic blood pressure in both dose and duration dependent manner. In each garlic treated group, significant reduction in SBP and DBP (p<0.005) were observed when compared with atenolol (P<0.005) and placebo.

Garlic (Allium sativum) supplementation with standard antidiabetic agent provides better diabetic control in type 2 diabetes patients.

Garlic has been used safely since ancient times as both food and medicine in human populations, but studies of its efficacy in the management of diabetes have yielded conflicting results. This study has evaluated the potential hypoglycemic effects of garlic in type 2 diabetic patients. The study was conducted in diagnosed type 2 diabetic patients (n=60) with fasting blood sugar level above 126 mg/dl to evaluate the effects of adding garlic tablets with standard antidiabetic therapy on blood sugar. Patients were divided randomly into 2 groups. Group 1 (n=30) was given tablet Garlic (KWAI) 300 mg thrice daily + Metformin 500 mg twice daily and Group 2 (n=30) was given Placebo+Metformin 500 mg twice daily respectively for 24 weeks. Serum lipids and fasting blood glucose were measured at week 0, 12 and week 24. Group1 showed significant reduction in fasting blood sugar at week 24 with a percentage decrease of (-3.12 percent) (P = <0.005) as compared to group 2 (0.59 percent). At the end of week 24, GR1 group also showed considerable decrease in mean total cholesterol (6.2 mg/dl, -2.82%, P=<0.005), LDL-C (-3 mg/dl, 2.18% P=<0.005), triglycerides (-5.2 mg/dl, 3.12%, P<0.005) while HDL cholesterol was significantly increased (2.36 mg/dl, 6.72%, P<0.005) as compared to GR2 group. Combination of garlic with typical antidiabetic remedy has shown to improve glycemic control in addition to antihyperlipidemic activity. Garlic may be a good addition in the management of patients with diabetes and hyperlipidemia.

Toxic effects of multiple anticancer drugs on skin.

In this study, cutaneous toxicities associated with the administration of chemotherapy in combination are discussed. Rapidly growing cells are the targets of chemotherapy, so the skin, hair follicles, and nail matrix are frequently affected by chemotherapy. Chemotherapy skin reactions are more likely toxic than allergic reactions. There are numerous chemotherapy-induced cutaneous reactions that have been described in the literature. In addition to a variety of miscellaneous reactions, 19 major cutaneous reactions were discussed in current study. This study was designed to evaluate the clinical spectrum of all cutaneous toxicities over two years in hospitalized and ambulatory patients in the Department of Pediatric oncology and to establish probable relationship between the reaction and suspected anticancer protocol with the help of WHO (World Health Organization) Common Toxicity Criteria by Grade. The data on the cutaneous toxicities were analyzed by percentile and ranking method. The minimal (0.8%) cutaneous adverse effects monitored during the study were Petechiae, photosensitivity, pruritus, urticaria, wound-infection, erythema multiforme, hand-foot skin reaction, injection site reaction, dry skin. Alopecia was the single most common (64.3%) adverse effect observed during the study, where as the pigmentary changes were the second most common (18.2%) adverse effect monitored. While these side effects are generally not life threatening, they can be a source of significant distress to patients, especially alopecia.

Synergism between collagen-adenosine diphosphate and collagen-epinephrine in platelets' aggregation: different dose response relationships.

OBJECTIVES: To evaluate the possible synergistic interaction of collagen-adenosine diphosphate and collagen-epinephrine in aggregation of human platelets. METHODS: An experimental study was carried out at Armed Forces Instiute of Pathology, Rawalpindi, Pakistan, from June 2001 to December 2002. The platelet aggregation was determined by means of turbidometric method, which measures changes in optical density of platelet suspension. After determining the sub-threshold values of each agonist with the help of dose-response curve, these agonists were added in pairs to determine the synergism between them. RESULTS: The differences between means of threshold and sub-threshold concentrations of agonists were significant (Collagen: P<0.001, ADP: P<0.001, Epinephrine: P<0.002). The responses of Collagen and Epinephrine in sub-threshold concentrations were synergistic in causing platelet aggregation, whereas there were no potentiating effects in response to that of Collagen and Adenosine diphosphate. CONCLUSION: The study reveals the synergistic potentiation of some of the agonists in circulation that might be responsible for the activated state of platelets and associated atherosclerotic complications.

Effects of garlic on dyslipidemia in patients with type 2 diabetes mellitus.

BACKGROUND: Garlic (Allium Sativum) has been used in herbal medicine for centuries for various ailments. In recent years garlic has been the focus of serious medical and clinical attention because of beneficial effects on several cardiovascular risk factors like reduction of serum lipids, blood pressure and plasma viscosity. There is also wide spread belief among general public that garlic has beneficial effects on cardiovascular system. The purpose of present study was to evaluate the effects of garlic on one of the major cardiovascular risk factors i.e. dyslipidemia in patients with type 2 diabetes mellitus. METHOD: This 12 week randomized, single-blind, placebo controlled study was conducted on Type 2 diabetic patients with newly diagnosed dyslipidemia (n=70). Patients were selected from Diabetic OPD of Jinnah Post Graduate Medical Centre, Karachi and were divided into two groups each comprising of 35 patients, they were given tablet garlic (Garlex-Bosch Pharmaceuticals) 300 mg (containing 1.3 % allicin) twice daily and identical placebo tablets respectively. Both groups were given diet and exercise plan. RESULTS: After 12 weeks the garlic treated group (n = 33) had a significant reduction in total cholesterol (-28 mg/dl, - 12.03 % P= <0.001), LDL - C (-30 mg/dl, - 17.99 % P=<0.001) while the placebo treated group ( n=32) had a non significant decrease in total cholesterol (- 2 mg/dl, - 0.9 % p= ns) and LDL-C (-3 mg/dl, -1.6 % p=ns). HDL cholesterol was significantly increased in patients treated with garlic (3.35 mg/dl, 8.81% P= <0.05) compared with placebo group (0.62, 1.6% P= n.s) but there was no significant difference in triglyceride was observed between two groups. CONCLUSION: This study suggests possible small short term benefits of garlic on dyslipidemia in type 2 diabetic patients. Garlic significantly reduced serum total cholesterol and LDL cholesterol and moderately raised HDL cholesterol as compared to placebo. Controlled Clinical Trials of longer duration are needed to assess the long term benefit of garlic on vascular and circulatory disease processes.

Comparison between duration dependent effects of Simvastatin and Gemfibrozil on dyslipidemia in patients with type 2 diabetes.

OBJECTIVE: To observe the duration dependent effects of two important classes of lipid lowering drugs i.e. simvastatin and gemfibrozil in type 2 diabetic patients with dyslipidemia in Pakistani population. METHODS: Seventy type 2 diabetic patients with newly diagnosed dyslipidemia were enrolled and were divided randomly into two groups each, with 35 patients. Group I patients was given tablets Simvastatin 20 mg once daily and group II patients received tablet Gemfibrozil 600 mg twice daily. The study period comprised of 12 weeks. Fasting lipid profile and fasting blood sugar was analyzed on week 0 (day of inclusion), week 6 and week 12. RESULTS: At week 12 simvastatin decreased serum LDL cholesterol by 36.97 percent (P < 0.001). In contrast gemfibrozil did not reduce it significantly with a reduction of only 1.33 percent (P = N.S). Simvastatin reduced serum total cholesterol and serum triglyceride by 29.88 percent (P < 0.001) and 21.78 percent (P < 0.001) respectively and increased serum HDL cholesterol by 16.67 percent (P < 0.001). While gemfibrozil decreased serum total cholesterol by 9.14 percent (P < 0.001) and serum triglyceride by 30.84 percent (P < 0.001). Gemfibrozil raised serum HDL cholesterol levels by 18.08 percent (P < 0.001). CONCLUSION: Significant changes were observed in all lipid parameters with both simvastatin and gemfibrozil with regard to duration of treatment. Simvastatin was found to be more effective in lowering serum total cholesterol and LDL cholesterol levels in comparison to gemfibrozil, which was found to be more effective in lowering serum triglyceride and elevating serum HDL cholesterol levels. Both of these drugs were well tolerated and none of the patients exhibited any significant adverse effects. Both can be given as monotherapy in patients with type 2 diabetes mellitus and abnormal lipid profile.
