A respiratory tract infection (RTI) is defined as any infectious disease of the upper and lower respiratory tract. Acute respiratory tract infection accounts for 12-35% of the in patients attendance in general hospital. A six months hospital based prospective observational study was carried out in the department of medicine at BTGH, Gulbarga. The aim of the study was to analyse the prescribing patterns of antibiotic in respiratory tract infection at medicine department. The study result showed that out of 90 patients, more prevalent LRTI were 86(95.5%), URTI were 4(4.5%) The COPD, pneumonia, asthma were more prominent among LRTIs, whereas pharyngitis and tonsillitis are prominent among URTIs. Results showed that for 90 patients 107 antibiotics were prescribed, most widely used antibiotics were penicillins + betalactams (38.31%). In our study the prescribers are relying upon higher antibiotics, this practise may lead to the antibioic resistance and other complications of antibiotic resistance. Prescription analysis shows the way towards rational use of drugs. Irrational drug use could also lead to ineffective and unsafe...

Calcium accumulation and calcium overload in the intracellular organelles has been known to be the main reason for cellular abnormalities related to oxidative stress. The study deals with the effects of an important calcium channel blocker (CCB)amlodipine in countering the hypoxia induced oxidative stress, in vitro and in vivo. We examined the intracellular calcium changes along withReactive Oxygen Species(ROS), lipid peroxidation by malondialdehyde(MDA) and reduced glutathione levels(GSH). Amlodipine displayed its maximum efficacy in attenuating oxidative damage during hypoxic insult of 0.5% hypoxia for 24 hours at concentration of 12.5nM. Amlodipine was also found effective in controlling apoptosis by maintaining Bax/Bcl-2 ratio, Cox-2 and VEGF levels significantly offering neuroprotective activity in N2a cells.In hypobaric hypoxia subjected (25,000 ft, 280mmHg and 28ᵒC for 24 h) Sprague Dawley (S/D) rats, intracellular calcium levels were found to be lowered significantly in amlodipine treated group (10mg kg-1 body weight) when compared to control group. Vascular leakage and brain water content were also found to be significantly decreased upon treatment with amlodipine compared to control...

Uvaria afzelii (UV) Sc Elliot (Annonaceae) locally is used in the treatment of kidney disorders, digestive problems, liver disorders, diabetes as well as gonorrhea. This study aims to investigate the possible hepatoprotective activities of the crude aqueous root extract of Uvaria afzelii against Paracetamol-induced hepatotoxicity with Silymarin being used as a reference standard. Twenty five (25) adult wistar rats were randomly assigned into a control group (A) and four treatment groups (B, C, D and E) each containing five rats (n=5/group). Animals in each group were allowed access to 200g/day growers’ mash and water ad libitum. Rats in the treatment groups were administered paracetamol orally at a dose of 800mg/kg body weight daily for fourteen days. Rats in group B were not pretreated while groups C, D and E rats were pretreated daily with 50mg/kg body weight of Silymarin, 250mg/kg and 500mg/kg body weight of crude aqueous extract of UV root respectively. The animals were sacrificed on the 15th day of the experiment and several serum markers, aspartate amino...

The present study reveals the chemical composition and mineral analysis of Curcuma amada, Alpinia nigra, Amomum gracile. They are belongs to the same family zingiberaceae. The result reveals; (a) alkaloid contains in Alpinia nigra (6.0mg/100gm), amomum gracile (0.6mg/100gm), Curcuma amada (4.280mg/100gm); (b) saponin contain in Alpinia nigra burtt(18.960mg/100gm), Amomum gracile (18.1mg/100gm) and Curcuma amada (21.22mg/100gm); (c) flavonoid contains in Alpinia nigra burtt (14.160gm/100gm), Amomum gracile (9.220mg/100gm) and Curcuma amada (8.400mg/100gm). The result of elemental analysis measure in ppb reveals; Alpinia nigra burtt contains iron (1.007 ± 0.001), Zn (0.408 ± 0.001), Cu (2.27 ± 0.08), Mo (0.011 ± 0.006), Cr (2.151 ± 0.0307) and Mn (0.013 ± 0.002), Amomum gracile was found to contains Fe (0.971 ± 0.046), Zn (0.414 ± 0.083), Cu (1.70 ± 0.03), Mo (0.013±0.004), Cr (5.091 ± 0.011) and Mn (0.015 ± 0.003) and Curcuma amada was found to contains Fe (0.954 ± 0.003), Zn (0.1764 ± 0. 0.005), Cu (1.80± 0.02), Mo (0.016 ± 0.008), Cr (1.643 ± 0.001) and Mn (0.014 ± 0.002)...

A rapid, sensitive and specific RP-HPLC method was developed and validated for determination of Rosuvastatin Calcium in bulk and tablet dosage form. Chromatography was carried out on a Enable C18G (250 x 4.6 mm i.d.,5µ) column using filtered and degassed mixture of acetonitrile and water in the ratio of 75:25 % v/v as mobile phase at a flow rate of 0.6 ml/min and effluent was monitored at 252 nm. The method was linear over the concentration range of 5 – 40 µg/ml with a correlation coefficient of 0.999. The retention time of the drug was 3.097 mins. The proposed method was validated by determining sensitivity, accuracy, precision, robustness studies. The developed method was effectively applied to tablets of Rosuvastatin Calcium and the % assay of the drug was found to be 99.98 %. The method is simple, rapid, accurate, precise and reproducible and hence can be applied for routine quality control analysis of Rosuvastatin Calcium in pure and tablet dosage...
