The animals were divided into four groups (n=6), graded doses (2.5, 5, and 10 mg/kg) of the extract. They were exposed to female rats in a ratio of 2:1 after 24 hours, 7, and 14 days of administration. The spermicidal properties were evaluated. The female contraceptive study involved 14 days of pre-coital and post-coital administration of the neem seed extract, and contraceptive indexes were investigated. The results obtained from the spermicidal activity showed a significant decrease in male hormonal levels at 2.5, 5, and 10 mg/kg of A. indica (0.73, 0.50, and 1.08 ng/ml); and the sperm cells (102.5, 111.5, and 97 counts) after 24 hours.

The histopathology of the treated uterus had no deteriorating effect compared with the control. The extract elicited spermicidal and contraceptive potential at a reduced dose, validating its folklore claim.","PeriodicalId":188261,"journal":{"name":"Biology, Medicine, & Natural Product Chemistry","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115655392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining Anthocleista vogelii and Alstonia boonei stem bark extract has effectively managed BPH and its associated complications. This study evaluated the effects of a combined Anthocleista vogelii and Alstonia boonei stem bark extract (CAASBE) on the lipid profile and renal functions of rats induced benign prostatic hyperplasia with testosterone propionate injection. The study comprised five treatment groups, with groups 1 – 5 being the normal control, BPH control, standard control, BPH+200 mg/kg CAASBE, and BPH+400 mg/kg CAASBE, respectively. BPH was induced in the groups 2 – 4 rats by subcutaneous administration of testosterone propionate injection (5 mg/kg) for 28 days, and treatment with Finasteride and CAASBE were administered orally. The BPH control rats exhibited a significant (p < 0.05) increase in the total serum cholesterol, triacylglycerol (TAG), low-density lipoprotein cholesterol (LDL-C), urea, creatinine and significant (p < 0.05) decline in the serum high-density lipoprotein cholesterol (HDL-C) compared to the normal control. Conversely, treatment of the BPH rats with 200 and 400 mg/kg of CAASBE significantly (p < 0.05) reversed the altered total serum cholesterol, TAG, LDL-C, HDL-C, urea and creatinine to normal levels comparable to that of the normal control and standard control respectively. These findings show that CAASBE alleviates hyperlipidaemia and renal malfunctions in the BPH rats suggesting it could be effective in managing BPH complication.","PeriodicalId":188261,"journal":{"name":"Biology, Medicine, & Natural Product Chemistry","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127232284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since March 2019, COVID-19 has been identified as a pandemic by the World Health Organization (WHO) and has infected millions of individuals worldwide. According to the literature review, endocrine disorders include diabetes, obesity, hypertension, and thyroid. The development and progress of COVID-19 patients could be affected but not yet approved by all the studies. In diabetes mellitus, COVID-19 may affect cytokines and increase releases of IL-1, IL-6, and complications caused by diabetes. In obese patients, there was an increased risk of progressing to severe COVID-19. Because of the international spread of severe acute respiratory syndrome coronavirus, clinicians should pay special attention to obese patients who should be monitored closely with timely and aggressive care. COVID-19 pathophysiology and risk in a high incidence of hypertension has been found in patients with COVID-19 and can be studied in many kinds of studies, such as in China. However, hypertension is considered one of the most significant risk factors for COVID-19. In addition to the above data on associations between COVID-19 and endocrine disorders, data on thyroid function or thyroid disease in COVID-19 is not yet available and cannot be commonly reported.","PeriodicalId":188261,"journal":{"name":"Biology, Medicine, & Natural Product Chemistry","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130384983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These varieties of Dioscorea analysed showed a significant difference (Pâ‰¤0.05) amongst them. However, from the results, it was observed that Dioscorea rotundata had the highest ash (8.05Â±0.05 %) and crude fibre content (13.11Â±0.10 %) which indicates that it contains more mineral stuffing and is best for softening of stool. Dioscorea cayenensis had the highest fat content (16.31Â±0.30 %), indicating that it is a better source of calories than other yam species analysed. Dioscorea dumenturom had the lowest moisture content (3.51Â±0.01 %) as well as the highest crude protein (12.29Â±0.01 %) and carbohydrates (69.04Â±0.10 %) than other yam species analysed, indicating its longer shelf-life, high bodybuilding capacity and better source of energy than other yam species analysed. The anti-nutritional constituent of alkaloid and tannin were lowest in Dioscorea cayenensis while Dioscorea rotundata had the least cyanide, phytate and oxalate content. This implies that these particular yams are safer for consumption. The elemental analysis in mg/100g indicated that the yam species contained appreciable levels of essential minerals, with Dioscorea dumenturom having the highest sodium, calcium, iron, potassium, phosphorous and magnesium concentration of 32.05Â±0.07 mg/100g,190.57Â±0.01mg/100g, 5.98Â±0.03 mg/100g, 80.12Â±0.17 mg/100g, 237.10Â±0.48 mg/100g and 100.22Â±0.03 mg/100g respectively.
