Methods We prepared various doses (100, 200, 400 mg/kg) of aqueous and methanolic leaf extracts for the antidiabetic study, and a dose of 2000 mg/Kg was prepared for the acute toxicity test. The first group that evaluated the hypoglycemic effect consisted of forty normoglycemic Wistar rats aged 7–8 months old with a weighted average of 265.8 ± 24.6 g. The second group consisted of intraperitoneal glucose-loaded male animals to evaluate the antihyperglycemic effect. The third group contained two groups of normoglycemic female rats (n = 3), aged 3 and 4 months old (weight average: 187.45 ± 14.82 g), treated for 14 days with aqueous and methanolic extracts (2 g/kg b.w) to assess mortality and toxic effects.

Objective To establish animal model for UP and AF and to evaluate polyherbal formulation, HPLF-111624 in these disease models. Methods An experimental model of UP was selected based on the modification of the ulcerative colitis model using different concentrations of acetic acid. The concentration used for induction were 2.5%, 5% and 10% v/v and different weights used to induce AF were 25 g, 50 g and 100 g, which were selected based on the severity of inflammation, fecal score, gross pathology, and histopathological evaluation. Furthermore, these animal models were used to evaluate the efficacy of HPLF-111624, a polyherbal formulation known to be beneficial in anal diseases. Results Acetic acid at 5% produced typical pathological changes that resembled UP, with a significant increase in the fecal score, gross lesion, and histopathological changes. Similarly, among the three weights, physical injury with a 100 g weight produced significant changes in the histopathological score in the model of AF. Intervention with HPLF-111624 at doses of 250 and 500 mg/kg b.wt., showed a reduction in the inflammatory cytokines and a significant improvement in the histopathological findings in both the conditions.

The condition may be persistent, increase in size and number, and have a high recurrence rate. There are many therapeutic options of AGW, but none of them prevented recurrence, only yielded partial responses and have the propensity to cause scars. Immunotherapy by purified protein derivative (PPD) is one of the therapeutic options for AGW, which effectively reduces the number of lesions until complete clearance, with minimal side effects and less recurrence rate. This case report aims to demonstrate the effectiveness, safety, and low recurrence rate of intralesional PPD injection as an alternative therapy for AGW. We reported one case of AGW in an immunocompetent 30-year-old homosexual man who was given 3 doses of 0.2 mL PPD injected intralesionally. As a result, clinical improvement was observed starting from the 18th day, with some of the lesions decreasing in size, and on the 46th day, all of the lesions disappeared. There was no significant side effect. Within two years of follow-up, no recurrence was observed. Intralesional injection of PPD can stimulate the immune response against human papillomavirus (HPV) infection both on the injection site and distant from the injection site. Previous studies have shown promising results of intralesional PPD, with low recurrence in over six-month follow-up and no side effects. Intralesional injection of PPD can be considered as an alternative therapy due to its minimal side effects and its long-term low recurrence rate.","PeriodicalId":15846,"journal":{"name":"Journal of Experimental Pharmacology","volume":"14 1","pages":"131 - 135"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44604769","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}
