Prevalence and treatment of HIV/AIDS in Pakistani population: A retrospective study.

HIV/AIDS epidemic poses an emerging threat around the world. An estimated 0.1% of people aged 15 to 49 years have been infected with HIV/AIDS in Pakistan during the last few years. This research study aims to analyse the prevalence and treatment/management of HIV/AIDS among the Pakistani population aged 15 to 45 years from 1990 to 2020 and this research data was collected during the year 2021. The analysis was done by using E-views software. Descriptive statistical analysis, correlation coefficient, unit root analysis, and linear regression analysis were used. Results indicated that there is low awareness regarding AIDS in the population and there is a significant link between prevalence and population increase, i.e. with the increase in population the prevalence of AIDS also increases. Findings are discussed in terms of implications for prevention and education of HIV/AIDS in Pakistan's population.

Antihypertensive effect of patulitrin and other constituents from Tagetes patula L. (French marigold) in acute L-NAME induced hypertensive rats.

The work is aimed to evaluate the blood pressure reducing effect of constituents from methanol extract and associated constituents of Tagetes patula flowers in normotensive and L-NAME induced hypertensive rats. The HPLC analysis of methanol extract of Tagetes patula flowers (JFM) resulted in the quantitative identification and percent comparison of four phenolic constituents, protocatechuic acid (PA), methyl protocatechuate (MPA), patulitrin (TRIN) and patuletin (PAT). All the extracts, fractions and compounds examined showed significant blood pressure lowering activity. Patulitrin (TRIN) which has emerged as the major constituent (15.33%) of T. patula flowers showed significant 30% and 68% fall in blood pressure in normotensive and L-NAME induced hypertensive rats respectively. The patuletin (PAT), which is an aglycone of TRIN displayed high percentage (84%) of antihypertensive activity. Further, comprehensive and advanced studies on these constituents may result in preparation of an effective blood pressure lowering medicine with active precious rare flavonoids, patuletin and patulitrin.

Report: Safety and toxicological evaluation of herbal formulation on rodents.

Herbal medicines are still most popular, abundant and affordable remedies for curing various ailments. Garlina is one of the herbal formulations of Hamdard Laboratories (waqf) Pakistan used to treat cardiovascular diseases and elevated sugar level. However, there is no scientific data available regarding the potential toxicity. Therefore, the present study was to assess the acute and sub-chronic toxicity in rats. The single dose of Garlina 5000mg/kg were administered orally and observed for 14 days. A sub-chronic toxicity test was performed at 2000mg/kg of Garlina daily for 30 days. Control rats received saline. The biochemical, hematological and histopathological analysis was carried out. The acute toxicity LD50 was determined to be <5000mg/kg. The result of acute and sub-chronic toxicity revealed no mortality and sign of toxicity. Garlina did not elicit any significant change in body weight, hematological and histopathology analysis when compared to saline treated rats. The relative weight of organs was not affected by the treatment. While the daily dose of Garlina for humans is 20mg/kg. However, the sub-chronic toxicity at 2000mg/kg dose of Garlina exhibited significant increase in gamma glutamyltransferase while total protein significantly decreased. Results obtained from study demonstrated that there is wide margin of safety for the therapeutic use of Garlina and significant decrease in LDL, atherogenic index, GGT and bilirubin direct at the dose of 5000mg/kg further strengthen the use as hypolipidemic and hypoglycemic agent.

Effect of cream containing Melia azedarach flowers on skin diseases in children.

A herbal cream containing a methanolic HPLC-standardized extract of Melia azedarach flowers has been prepared and found potent against bacterial skin diseases like cellulitis, pustules, pyogenic infections, etc. in children. The results obtained are comparable to those with neomycin.

Healing potential of cream containing extract of Sphaeranthus indicus on dermal wounds in Guinea pigs.

A cream containing ethanolic extract of aerial parts of Sphaeranthus indicus, Linn. (Asteraceae) was evaluated for wound healing activity in guinea pigs. The cream was applied in vivo on the paravertebral area of six excised wounded models once a day for 15 days. The cream significantly enhanced the rate of wound contraction and the period of epithelialization comparable to neomycin.
