RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Solenostemma argel is widely distributed in Africa & Asia with traditional usage in alleviating abdominal colic, aches, & cramps. This plant is rich in phytochemicals, which must be explored for its pharmacological effects. PURPOSE: Peptic Ulcer Disease (PUD) is the digestion of the digestive tube. PUD not only interferes with food digestion & nutrient absorption, damages one of the largest defensive barriers against pathogenic micro-organisms, but also impedes drug absorption & bioavailability, rendering the oral route, the most convenient way, ineffective. Omeprazole, one of the indispensable cost-effective proton-pump inhibitors (PPIs) extensively prescribed to control PUD, is showing growing apprehensions toward multiple drug interactions & side effects. Hence, finding a natural alternative with Omeprazole-like activity & limited side effects is a medical concern. STUDY DESIGN: Therefore, we present Stemmoside C as a new gastroprotective phytochemical agent isolated from Solenostemma argel to be tested in upgrading doses against ethanol-induced gastric ulcers in mice compared to negative, positive, & reference Omeprazole groups. METHODS: We carried out in-depth pharmacological & histopathological studies to determine the possible mechanistic pathway. RESULTS: Our results showed that Stemmoside C protected the stomach against ethanol-induced gastric ulcers parallel to Omeprazole. Furthermore, the mechanistic studies revealed that Stemmoside C produced its effect using an orchestrated array of different mechanisms. Stemmoside C stimulates stomach defense by increasing COX-2, PGE-2, NO, & TFF-1 healing factors, IL-10 anti-inflammatory cytokine, & Nrf-2 & HO-1 anti-oxidant pathways. It also suppresses stomach ulceration by inhibiting leucocyte recruitment, especially neutrophils, leading to subsequent inhibition of NF-κBp65, TNF-α, IL-1ß, & iNOS pro-inflammatory cytokines & JAK-1/STAT-3 inflammation-induced carcinogenicity cascade in addition to MMP-9 responsible for tissue degradation. CONCLUSION: These findings cast light on Stemmoside C's clinical application against gastric ulcer progression, recurrence, & tumorigenicity & concurrently with chemotherapy.

Objective: To evaluate the efficacy of castor oil in initiation of labor in women who had one previous cesarean section. This study was conducted as a trial to increase the rate of vaginal birth after cesarean (VBAC) and decrease the rate of elective repeated cesarean section (ERCS).Methods: A double-blinded randomized controlled study was conducted in an Egyptian University Hospital from July 2019 to July 2020. The participants were 70 pregnant women who had one previous cesarean section, singleton pregnancy in cephalic presentation, with a Bishop score ≤6 attempting to perform a trial of labor. Sixty mL castor oil was administered to group A and 60 mL sunflower oil was administered to group B (as a placebo) for initiation of labor at the start of week 39. Primary outcomes were the percentage of women entering the active phase of labor within 24 h after receiving castor oil or placebo and the number of successful VBAC deliveries.Results: Labor started in 16 patients (45.7%) within 24 h in the castor oil group and in 3 patients in the placebo group (8.5%), while the rate of successful VBAC was 65.7% (23 patients) in the castor oil group and 48.5% (17 patients) in the placebo group.Conclusion: Castor oil appears to be an effective, low-cost, and non-harmful method for the initiation of labor in patients with a previous cesarean section.

Almost one-third of the people suffering from epilepsy continue to have seizures in spite of using appropriate antiepileptics. Pharmacoresistance is defined as the failure to achieve seizure control with two or more anticonvulsant medications at appropriate daily dosage. Here, we discuss one such gentleman whose seizures had been intractable despite multiple antiepileptic drugs in maximum tolerable doses. Verapamil, a calcium channel blocker, was used for its P-glycoprotein inhibition properties to overcome the pharmacoresistance in this patient with satisfactory seizure control. There are a few studies with limited patients on the successful usage of verapamil in a patient with pharmacoresistant status epilepticus (SE). We intend to publish this case report to draw interest among the critical care physicians on pharmacoresistant SE, the different hypotheses that prevail, its causes and the available management strategies.
