In vivo evaluation of efficacy and safety of Coagulansin-A in treating arthritis.

The current study aimed to determine the safety and efficacy of Coag-A through in vivo analysis in CFA induced mice model. Treatment of CFA induced arthritis in mice with Coagulansin-A (10 mg/kg i.p. daily for 28 days), a withanolide obtained from Withania coagulans, as well as standard drug treatment with Dexamethasone (5 mg/kg i.p) was provided. The effect of Coag-A on body weight, relative organ weight, hematology, serum biochemistry, survival rate, oxidative stress markers, and antioxidant enzymes was evaluated. The liver and kidney histopathology were also assessed to ascertain its safety profile. Treatment of arthritic mice with Coag-A considerably improved body weight, relative organ weight of liver, kidney, and spleen, ameliorated hematology and serum biochemistry, and increased survival and antioxidant potential. Coag-A was found to be safer with fewer adverse effects showing hepato-protective, nephroprotective, and anti-inflammatory effect. It also significantly (p < 0.001) improved histopathology of CFA-induced mice when compared with Dexa. In conclusion, compared to dexamethasone, Coag-A has demonstrated a greater therapeutic benefit and fewer side effects in the treatment of arthritis against the CFA-induced model.

Comparative appraisal of in vitro biological profile and in vivo wound healing attributes of bergenin and Bergenia ciliata (Haw.) Sternb.

ETHNOPHARMACOLOGICAL RELEVANCE: People of all ages experience injuries, whether mild or severe. The most available option to treat wounds as an alternative to allopathic care in both urban and rural populations is traditional medicine, which is mostly target inflammation. Bergenia ciliata (Haw.) Sternb rhizome and leaf powder are used in Ayurveda and local communities for various ailments including healing of wounds and burns. Owing to this property it is traditionally known as "Zakham-e-hayat" (wound healer). AIM OF THE STUDY: In the present study, we compared biological activity and wound healing potential of B. ciliata rhizome (R) extract and bergenin, a glycoside isolated from B. ciliata. MATERIALS AND METHODS: Reverse-phase high performance liquid chromatography (RP-HPLC) was performed to analyze polyphenols and bergenin in B. ciliata R extract. Samples were subjected to in vitro antioxidant assays including free radical scavenging, ferric chloride reducing power and total antioxidant capacity. Micro-broth dilution method, brine shrimp lethality assay and isolated RBC hemolysis assay were conducted to assess in vitro antibacterial and cytotoxic activities. Moreover, in vivo wound healing potential was determined by an excision wound model in mice. RESULTS: RP-HPLC showed significant content of polyphenols and bergenin (6.05 ± 0.12 µg/mg) in B. ciliata R extract. Crude extract possesses higher overall antioxidant and antibacterial capacities than bergenin due to presence of multiple phytoconstituents in extract. Both samples showed low hemolytic activity indicating their safe profile. Furthermore, mice treated with B. ciliata R extract depicted substantial decrease in wound area (99.3%; p < 0.05) as compared to bergenin, which showed 88.8% of wound closure after 12 days of treatment. Additionally, both treatments reduced epithelization duration by 1.6- and 1.4-fold in B. ciliata R extract (12.0 ± 0.6 days) and bergenin (14.2 ± 0.8 days) treated mice, respectively. This was supported by histopathological examination that showed greater epithelization, fibroblast proliferation, collagen synthesis, and revascularization in mice treated with B. ciliata R. CONCLUSION: Concisely, it is evident that B. ciliata R contains phytoconstituents in addition to bergenin, which potentiated wound healing activity of the extract. Hence, B. ciliata R is good source of compounds for treating wounds.

Primary Ovarian Burkitts Lymphoma.

Primary ovarian Burkitt lymphoma (BL) is a very rare and aggressive malignancy. We report an 18-year-old female patient who presented with a large, tender abdomen, and highly de-ranged renal and liver functions. Ultrasonography showed hepatosplenomegaly, mild ascites, dilated biliary channels and a heterogeneous pelvic mass of size ~15106.4 cm. Immunohistochemical (IHC) staining of the biopsy sample excised from the left ovary demonstrated reactivity for CD20 and CD10, and negativity for CD3, Bcl-2 and TdT. The C-myc translocation was positive in 60% of tumour cells. Moreover, the proliferation index was ~90%. These features were consistent with BL. After haemodialysis, the patient was planned for multiagent chemotherapy, including cyclophosphamide, doxorubicin, vincristine and prednisone. This case supports the hypothesis that primary ovarian BL is an aggressive malignancy that appears to respond promisingly to multi-agent chemotherapy.
