Objective: The aim of this study is to evaluate anti-oxidant and anticancer activity of methanol extract and ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark against the hepatocellular carcinoma. Materials and methods: DPPH and H2O2 free radical scavenging assay were tested for determining the anti-oxidant activity. Rat normal liver cells (BRL-3A) and human hepatocellular carcinoma (Hep3B) cells were tested in-vitro for cytotoxicity using (3-4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. Result: Ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark exhibited significant DPPH and H2O2free radical scavenging activity withIC50 value (µg/ml) of 10.58 and 11.89 as compared to standard drug ascorbic acid. Ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark exhibited significant cytotoxicity against human hepatocellular carcinoma (Hep3B) cells in-vitrowithIC50 value (µg/ml) of 32.55 as compared to standard doxorubicin (55.43µg/ml), and not affected the normal liver (BRL-3A) cells. Conclusion: Symplocos racemosa bark showed the potent anti-oxidant and anticancer activity. It may be due to presence of phytochemicals which are responsible for the anticancer...

In this study, we assessed the availability, cost and affordability of essential antibiotics for paediatrics in a semi-rural region in Tanzania. Data were collected from 1 Medical Stores Department (MSD), 8 public hospitals, 30 Private Pharmacies and 30 Accredited Drug Dispensing Outlets (ADDO`s). The median price of tracer medicines and average stock-out days of per year were used to assess the cost and availability of medicines in the health facilities, respectively. The salary of the lowest paid unskilled government worker and national poverty line income were used to assess affordability of medicines. The median availability of the lowest-price generics of essential antibiotics for paediatrics in the pharmacies, ADDO’s and public hospitals was 59.09%, 62.5%, and 45.5%, respectively. At MSD, only 13 out of the 22 antibiotics were in stock at the time of survey. The median stock out days was 124 days per year. The median price ratios (MPRs) of retail patient’s prices for 20 generic antibiotics were 1.774 for 30 pharmacies, while for 8 generic antibiotics in 30...

Objective: to investigate the anti diabetic effect of ethanolic extract of Cinnamomum zeylanicum on Alloxan induced diabetes in experimental animals (Rats). Materials and Methods: the alcohol extract of Cinnamomum zeylanicum was tested for its efficacy in Alloxan (150mg/kg) induced diabetic rats. The diabetic rats were divided into 5groups. Group I (control) received 2% gumacasia, group II (positive control) received standard drug Glibenclamide (10mg/kg+2%GA), group III, IV, V (T1 T2 T3) were treated orally with a daily dose of 50mg/kg, 100mg, 200mg, respectively for 30 days, for all diabetic rats after giving TEST, NC, PC preparations, the blood samples were collected & the blood glucose levels determined at 0, 1…, 0 hr reading is before giving the drug & the remaining three readings after giving the drugs. 24th hr reading is considered as 0hr reading for the next day. Results: administration of alcohol extract of Cinnamomum zeylanicum produced a dose dependent decrease in blood glucose levels in Alloxan induced rats. There was significant fall in blood sugar level in High...

The pharmacological activity of Withenia somnifera commonly called Ashwagandha, a herb having multi-medicinal properties, was investigated against carbofuran exposed hepatic anomalies in the air breathing fish Clarias batrachus. Fishes were exposed to 1 mg/L carbofuran for three weeks to induce the toxic effects. These fishes were then fed with Withenia somnifera root extract mixed pelleted feed @ 10% of the total feed ingredients for the next 6th and 8th week respectively. The histopathological examination of hepatic tissues was done on light microscopy and transmission electron microscopy. Major changes attributed to the hepatic cells after carbofuran treatment showed irregular shape of hepatic cells, increased sinusoidal spaces, rough endoplasmic reticulum, secretary granules, dilated mitochondrial cristae and presence of kupffer cells. Amoeboid nucleus with increased heterochromatin material, granular nucleoplasm and enlargement of nucleolus, were some of the prominent histopathological alteration in the liver tissue after carbofuran toxicity at transmission electron microscope (TEM) level. The histopathological examination of liver cell of carbofuran exposed fish followed by administration of W.somnifera root extract mixed pelleted...

Introduction: A bidirectional relationship exists between type 2 diabetes mellitus (T2DM) and depression. There is dearth of research on comparative suitability of different antidepressants in people with T2DM and depression. Aim: To compare the effects of Escitalopram and Agomelatine on glycemic control and symptoms of depression in patients with T2DM and depression. Materials and Methods: We conducted a randomized, open label, parallel groups study. Patients diagnosed as T2DM with moderate to severe depression (Hamilton Depression Rating Scale Score ≥ 14) were randomized to receive either Escitalopram (10 mg daily) or Agomelatine (25 mg daily) along with antidiabetic agents as per American Diabetes Association (ADA), 2013 guidelines. Depression was assessed using HDRS and Montgomery Asberg Depression Rating Scale (MADRS). Results: Escitalopram group showed a significant reduction in FBG and HbA1Cvalues as compared to Agomelatine group at 1 and 2 months. HDRS scores of Escitalopram group were significantly lower than Agomelatine group at 1 and 2 months (8.85 ± 5.86 and15.6 ± 2.5 respectively). Similarly, Escitalopram group showed significantly lower MADRS...
