Diuretic and anti-diarrheal potential of four fruit extracts of Capsicum annum L.

Capsicum has been an important part of diet since centuries and has been widely used traditionally for ailments. The objective of the present analysis was to determine the diuretic and antidiarrheal potentials of four variations of Capsicum annum L. fruits available in local market of Karachi, Pakistan. It belongs to family Solanaceae and extracts were prepared in 95% ethanol and was given in doses of 200 and 400mg/kg and the activity was correlated with commonly used diuretics and anti-diarrheal further reinforcing its conventional use. Fruits extracts were evaluated for anti-diarrheal properties in castor-oil induced diarrhea to confirm its activity. The diuretic activity of the 95% ethanolic extracts of Capsicum annum L. was assessed based on diuresis of 24 hr. collected through metabolic cage. Urinary excretion of water and electrolytes (Na+ and K+) is significantly increased by the standard diuretic drug furosemide, which is comparable with the extract. The anti-diarrheal effects of 95% ethanolic extracts of Capsicum annum L. were examined by castor oil induced diarrhea and all varieties of Capsicum annum L. significantly inhibited the number of defecations.

Analgesic and anti-inflammatory potential of four varieties of bell pepper (Capsicum annum L.) in rodents.

The aim of study was to evaluate the analgesic and anti-inflammatory activity of four different colored (green, yellow, orange and red) sweet bell peppers (Capsicum annuum L.) available in the local market of Karachi Pakistan. Their 95% ethanol extracts at 200 and 400 mg/kg were prepared and compared with commonly used analgesic (aspirin) and anti-inflammatory agents supporting its traditional use. The analgesic effects of 95% ethanol extracts of Capsicum annum L. were investigated by acetic acid induced writhing, tail immersion and hot plate test. The anti-inflammatory activities were observed using carrageenan-induced edema of hind paw in rats. Animals were divided into 10 groups (n=7): (1) Control (2) CAG 200 (3) CAG 400 (4) CAR 200 (5) CAR 400 (6) CAO 200 (7) CAO 400 (8) CAY 200 (9) CAY 400 and (10) Standard. All the extracts were given orally. Acute toxicity was also determined by increasing the dose till 3000 mg/kg, which showed no evidence of mortality. All extracts of Capsicum significantly increased the hot plate pain threshold, moreover remarkably reduced the carrageenan-induced rat paw edema. Results obtained were compared with corresponding control group revealed that the fresh fruits extract of all four kinds of bell pepper (200 mg/kg and 400mg/kg) possess anti-inflammatory and pain suppressing activities possibly mediated via PG synthesis inhibition.

A Rare Presentation of Type-III Takayasu's Arteritis in a 20-Year-Old Female.

Takayasu's arteritis is a rare chronic granulomatous vasculitis that predominantly affects the aorta and its branches. It is estimated to affect 2.6/million/annum, predominantly women in the second or third decade of their lives. This case report describes the case of a 21-year-old female, who initially only had low-grade fever and acrodynia, which over a few months, progressed to arm and leg claudication, weight loss, nausea, headache, and dizziness. A year later, the patient experienced impalpable radial pulses bilaterally, and her CT angiogram revealed multi-level arterial stenosis. A diagnosis of Takayasu's arteritis was made and the patient was started on steroids and methotrexate. A consult was made with vascular surgery but no intervention was deemed necessary and the patient responded well to the medical treatment given. Though Takayasu's arteritis is a very rare disease, a detailed history, clinical examination, and investigations can help with early diagnosis.
