- چکیده انگلیسی: Objective: Eleutherine palmifolia (L.) Merr. extract (EPE) containing isoliquiritigenin and oxyresveratrol is believed to be an anticancer agent. This study evaluates colon histopathology, TNF-α, TGF-β, and hepatotoxicity on BALB/c mice colitis-associated colon cancer (CAC) model treated with EPE. Methods: In vivo study was performed on BALB/c mice CAC model induced by 10 mg/kgBW AOM on the first day followed by administration that each cycle consisted of 5% DSS in water for seven days and regular water for seven days. The indicators of the formation of CAC were observed by a fecal occult blood test (FOBT) and serum amyloid α (SAA) test. The treatment was conducted once a week started from the seventh week up to the twentieth week with six treatment groups: I was administrated by regular water only (negative control), II was administrated by AOM and DSS only (positive control), III was administrated by doxorubicin, IV-VI were treated by EPE (0.25 mg/kg BW, 0.50 mg/kg BW, and 1.00 mg/kg BW) respectively. The colon and liver’s histopathology was observed using hematoxylin-eosin (HE) staining, TNF-α with immunohistochemistry (IHC), and level measurement of TGF-β colon with ELISA reader. The data were used one-way ANOVA followed by post hoc as statistical analysis. Results: The administration of EPE increased the expression of TNF-α, the total of goblet cells of the colon, and decreased the level of TGF-β. Administration of EPE 0.50 mg/20g BW decreased a liver histopathological score but induced a histopathological alteration of the liver at a dose of 1.00 mg/20g BW. Conclusion: This study indicate that EPE could be recommended as a colon anticancer through increase the goblet cells, induce apoptosis through increase TNF-α, and decrease TGF-β.

- چکیده:
- چکیده انگلیسی: Background: Scorpion sting envenomation generally causes treatable local and systemic effects; however, in rare cases, the victims might experience sequels in end organs such as central nervous system. In the present paper, a case of relatively self-limiting demyelinating polyneuropathy following a Butidae sting is presented and the possible mechanisms are discussed. Case Presentation: A 19-year-old man presented to emergency department of Sultan Qaboos University Hospital, Oman with severe throbbing pain at the base of his right big toe after a scorpion sting. His initial examination revealed normal vital signs and the systemic examinations were unremarkable. Few minutes later, he developed profuse sweating, slurred speech, blurred vision, increased salivation and restlessness. Repetition of measurement of vital signs showed a blood pressure of 160/100 mmHg, heart rate of 140 beat per minute and a respiratory rate of 18 per minute. The patients received scorpion antivenom and cholinergic hyperactivity manifestations. Shortly after, the patient developed involuntary jerky movements in both lower associated with fasciculation. Nerve conduction study was suggestive of demyelinating polyneuropathy. In later days, involuntary jerky movements of lower limbs improved gradually but fasciculation remained. On a follow-up visit after four months, the patient still complained of occasional fasciculation. Discussion: One explanation for the development of peripheral nerves demyelination in our patient is the inflammatory response triggered by scorpion venom. In addition, this complication can be attributed to direct cytotoxic effects of scorpion venom toxins. Antimicrobial peptides in scorpion venoms are shown to be highly toxic to human cells, which in our case might have damaged the nerve sheet. Conclusion: Severe scorpion sting envenomation may lead to severe systemic effects and end organ damage. Medical toxicologists should be prepared to diagnose and treat such sequels.
