GC-MS Analysis: In Vivo

Liver disease is a worldwide problem. It represents one of the main causes of morbidity and mortality in humans. Achillea biebersteinii is used as herbal remedy for various ailments including liver diseases. But the scientific basis for its medicinal use remains unknown. Thus, this research was undertaken to evaluate the efficiency of A. biebersteinii essential oil (ABEO) (0.2 mL/kg) in the amelioration of CCl4-induced hepatotoxicity in rodent model. Moreover, the chemical content of the oil was investigated using GC and GC-MS. The following biochemical parameters were evaluated: serum glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), gamma-glutamyl-transpeptidase (γ-GGT), alkaline phosphatase (ALP), and total bilirubin. Furthermore, lipid profile, malondialdehyde (MDA), nonprotein sulfhydryl (NP-SH), and total protein (TP) contents in liver tissue were estimated. 44 components (92.0%) of the total oil have been identified by GC-MS analysis where α-terpinene and p-cymene were the most abundant. The high serum enzymatic (GOT, GPT, GGT, and ALP) and bilirubin concentrations as well as the level of MDA, NP-SH, and TP contents in liver tissues were significantly reinstated towards normalization by the ABEO. Histopathological study further confirmed these findings. In addition, ABEO showed mild antioxidant activity in 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and β-carotene-linoleic acid assays

Medial canthus retiform hemangioendothelioma

Retiform hemangioendothelioma (RH) is a distinct entity in the spectrum of vascular tumors with a high local recurrence rate. It is considered a low-grade, well-differentiated cutaneous angiosarcoma with low metastatic potential. We report here for the first time a case of medial canthus recurrent RH. It may be helpful in our practice to include RH as a differential diagnosis of eyelid lesions. It is noteworthy that the progressive course and recurrence tendency of RH might be misdiagnosed as angiosarcoma or basal cell carcinoma (BCC), if not expected and carefully evaluated by the pathologist

Treatment with Rhus tripartita extract curtails isoproterenol-elicited cardiotoxicity and oxidative stress in rats

BACKGROUND: Consumption of plant-derived nutraceuticals and crude drugs in traditional medicine is widely believed to confer beneficial effects in thwarting the progression of cardiovascular diseases. Rhus tripartita (family Anacardiaceae) has been traditionally used to treat a wide range of ailments. METHODS: In the present study we investigated the protective effects of an alcoholic extract of the stem part of Rhus tripartita male genotype (RTSM) on experimentally induced myocardial injury in rats. To this end, cardiac injury was induced by administration of isoproterenol (ISO) and serum enzyme markers, lipid profiles and cardiac tissue redox status were determined following RTSM treatment (250 and 500 mg/kg). RESULTS: As a result, RTSM treatment significantly mitigated ISO-triggered upregulation of cardiac-specific markers of injury creatine kinase and lactate dehydrogenase. RTSM treatment significantly attenuated ISO-induced increase in serum cholesterol and triglycerides as well alterations in serum lipoproteins. Determination of oxidative balance showed that RTSM treatment significantly blunted ISO-induced increase in malondialdehyde and decrease in nonprotein sulfhydryl in cardiac tissue. Six compounds were isolated and identified as gallocatechin 1, taxifolin 2, myricetin-3-O-β-glucoside 3, catechin 4, epicatechin 5, and 3′,8-binaringenin 6. Compound 6 was isolated for the first time from the stem part of Rhus tripartita. Furthermore, RTSM treatment enhanced the survival fraction of cardiac cells exposed to oxidative stress in vitro. CONCLUSION: We conclude that the antioxidant properties of RTSM treatment underpin its cardioprotective pharmacological effects, thus, providing biological evidence for the treatment of cardiovascular diseases using Rhus tripartita in indigenous medicine
