RESUMO
Hematohidrosis is an uncommon pathophysiological condition of sweating blood. A young lady with abrupt bleeding from the skin (since January 2017) was brought to the emergency. The bleeding was vanished after mopping with no site of injury, but it reappeared soon enough confirming its nature. Bleeding time (BT), clotting time (CT), and the prothrombin time (PT) was within normal limit. This patient is confirmed as a case of hematohidrosis by the method of exclusion and the presence of blood was finalized by benzidine test as well as biochemical and microscopic examination of it. Now, no treatment is available as per the latest pieces of evidence. Also, the cause of it is not known till date. Psychological anxiety is a predisposing cause for hematohidrosis.
RESUMO
Aluminium toxicity is a major deterrent for plant growth in acid soils below pH 5.0. This study deals with effect of aluminium toxicity on growth of mungbean (Vigna radiata L. Wilczek) seedlings. Seed germination (in %) declined with increased content of Al2(SO4)3, while promotive effect was observed at very low dosage. Different concentrations of aluminum sulphate salt were applied to mungbean seeds. Measurement of aluminium content in mungbean leaves was done through atomic absorption spectrophotometer. Root length (root and hypocotyl length) and shoot length (shoot and epicotyl length) was measured at seven days old seedling stage. Different concentrations of Al2(SO4)3 were found to have significant effect both on shoot and root length. Leaf area, fresh and dry weight was significantly reduced. Increased stomatal frequency and trichome density with an increase in concentrations of Al2(S04)3 was observed through scanning electron microscope.
