Human protein reference database--2006 update.

Human Protein Reference Database (HPRD) (http://www.hprd.org) was developed to serve as a comprehensive collection of protein features, post-translational modifications (PTMs) and protein-protein interactions. Since the original report, this database has increased to >20 000 proteins entries and has become the largest database for literature-derived protein-protein interactions (>30 000) and PTMs (>8000) for human proteins. We have also introduced several new features in HPRD including: (i) protein isoforms, (ii) enhanced search options, (iii) linking of pathway annotations and (iv) integration of a novel browser, GenProt Viewer (http://www.genprot.org), developed by us that allows integration of genomic and proteomic information. With the continued support and active participation by the biomedical community, we expect HPRD to become a unique source of curated information for the human proteome and spur biomedical discoveries based on integration of genomic, transcriptomic and proteomic data.

Antidiabetic, antihypercholesterolaemic and antioxidant effect of Ocimum sanctum (Linn) seed oil.

Antihyperlipidaemic and antioxidant effect of Ocimum sanctum Linn. seed oil (OSSO) was investigated in rabbits. Administration of OSSO (0.8 g/kg body weight/day) for four weeks, in cholesterol (100 mg/kg body weight/day) fed rabbits significantly decreased serum cholesterol, triacylglycerol and LDL-+VLDL-cholesterol as compared to untreated cholesterol fed group. There was significant fall in atherogenic index in OSSO treated group. In addition, treatment with OSSO decreased lipid peroxidation and increased reduced glutathione content in blood. Antidiabetic effect of O. sanctum seed oil was evaluated in alloxan diabetic rabbits. Two weeks treatment of diabetic rabbits with OSSO (0.8 gm/kg/day) showed no significant hypoglycaemic effect. Results of the present study show that OSSO has hypocholesterolaemic and antioxidant effects but it does not have antidiabetic effect.

Antioxidant effect of aqueous extract of the bark of Ficus bengalensis in hypercholesterolaemic rabbits.

The antioxidant effect of aqueous extract of the bark of Ficus bengalensis has been evaluated in hypercholesterolaemic rabbits. Rabbits were divided into three groups, Group I served as healthy control; groups II and III were made hypercholesterolaemic by feeding cholesterol suspended in groundnut oil (100 mg/kg body weight per day) for 6 weeks. Rabbits of Group III received water extract of the bark of Ficus bengalensis at a dose of 50 mg/kg body weight per day in addition to cholesterol suspended in oil. Feeding cholesterol increased serum cholesterol, triacylglycerol and LDL + VLDL-cholesterol significantly in Group II as compared to Group I (P = 0.001). Treatment with water extract decreased the serum cholesterol level by 59%, triacylglycerol by 54% and LDL + VLDL-cholesterol by 60% in Group III as compared to Group II. In addition, treatment with this extract led to a decrease in lipid peroxidation as evidenced by fall in thiobarbituric acid reactive substances with a corresponding increase in blood glutathione content (P = 0.001). Further, there was significant increase in the activities of antioxidant enzymes; superoxide dismutase (P < 0.001), catalase (P < 0.03), glutathione peroxidase (P = 0.03) and glutathione reductase (P < 0.01); which were depressed in Group II rabbits after cholesterol feeding. Thus, our results show that the water extract of the bark of Ficus bengalensis has significant antioxidant effect, in addition to hypolipidaemic effect.

A study of prevalence of Chlamydia trachomatis infection in women with first trimester pregnancy losses.

The study included 125 patients in the first trimester of pregnancy, who were divided into group A (50 control subjects with normal intrauterine pregnancy), Group B (50 patients with spontaneous abortion), group C (25 patients with ectopic pregnancy). All the patients were investigated including routine blood and urine tests and special tests related to the cause of pregnancy loss. The patients were tested for IgG antibodies to Chlamydia trachomatis by ELISA technique and conjunctival smear were tested for presence of inclusion bodies to C. trachomatis. It was concluded that C. trachomatis is one of the important cause of spontaneous abortion and ectopic pregnancy. It is highly prevalent in our population, the prevalence being 10% in group A, 26% in group B, 28% in group C. Conjunctival smear showed presence of inclusion bodies in 0.8% patients. With abortions then risk of lower genital tract chlamydia infection spreading to upper genital tract increases. ELISA for C. trachomatis should be done when women are being investigated for the cause of spontaneous abortion and ectopic pregnancy.

An unusual case of complete heart block with triplet pregnancy.

A young primigravida presented at 36 weeks of gestation with complete heart block and triplet pregnancy. She underwent a lower segment cesarean section, and was managed successfully. The patient remained asymptomatic and did not require antiarrhythmic drugs or pacing.
