TL;DR: Aqueous extract of flowers of Butea monosperma showed its protective effect on biochemical and histopathological alterations at all the three doses in dose dependent manner and maximum improvement in the histoarchitecture was seen at higher dose of BM extract.

TL;DR: The purpose of this study was to define further the basis of control of myocardial membrane permeability by further examination of the “calcium paradox,” and the protective effect of hypothermia and addition of micromolar amounts of divalent cations during the Ca-free perfusion period were studied.
Abstract: The purpose of this study was to define further the basis of control of myocardial membrane permeability by further examination of the "calcium paradox." To this end, the protective effect of hypothermia and addition of micromolar amounts of divalent cations during the Ca-free perfusion period were studied. Damage during Ca++ repletion to the isolated arterially perfused, interventricular rabbit septum was assessed by contracture development, loss of developed tension, and loss of 42K and creatine kinase. Progressive hypothermia prolongs the time of Ca-free perfusion needed to cause similar 42K, creatine kinase and developed tension losses upon Ca++ repletion. Complete protection against the Ca-paradox after 30-60 minutes Ca-free perfusion is seen at 18 degree C. The inclusion of 50 microM Ca++ during 30 minutes "Ca-free" perfusion also provides complete protection during Ca++ repletion i.e., there was full mechanical recovery with no 42K or creatine kinase loss. Other divalent cations perfused in 50 microM concentrations during the Ca-free period exhibited variable ability to protect when Ca++ was reperfused. The order of effectiveness (Ca++ greater than Cd++ greater than Mn++ greater than Co++ greater than Mg++) was related to the crystal ionic radius, with those cations whose radii are closest to that of Ca++ (0.99 A) exerting the greatest protective effect. The cation sequence for effectiveness in Ca-paradox protection is the same sequence for potency of excitation-contraction uncoupling. The mechanism of hypothermic protection is likely a phase transition in the membrane lipids (from a more liquid to a less liquid state) which stabilizes membrane structure and preserves Ca++ permeability characteristics during the Ca-free period. The mechanism of protection via cation addition is perhaps a cation9s ability to substitute for Ca++ (dependent on unhydrated crystal ionic radius) at critical sarcolemmal binding sites to preserve control of Ca++ permability during the Ca-free period.

TL;DR: The extract caused selective changes in some biochemical parameters of organ function; however, since only mild alteration was observed at a dose of 300 mg/kg, the garlic bulb may be considered to be relatively safe and could be explored as an oral remedy at this dose.
Abstract: Objective To evaluate the antimicrobial and toxicological effects of aqueous garlic (Allium sativum) bulbs extract in wister rat using biochemical and hematological parameters. Methods A total of 20 wister rats were assigned into four (A–D) groups of five animals each. Group A served as the control and was administered 1 mL of distilled water. Groups B–C were given 300, 600 and 1 200 mg/kg body weight of garlic (Allium sativum) bulbs extract for 5 weeks. Results Garlic bulbs extract produced significant inhibitory activities against all bacteria tested at concentrations of 120 and 160 mg/mL. However, at concentration of 80 mg/mL, the extract had no inhibitory activities against Klebsiella pneumoniae and Salmonella typhi. The minimal inhibitory concentration and minimal bactericidal concentration ranged between 80–120 mg/mL and 120–160 mg/mL respectively. Toxicological study revealed that the extract did not cause any significant (P > 0.05) alteration to serum aspartate transaminase, alkaline phosphatase activities, total bilirubins, Na, K, creatinine, red blood cell, hematocrit, hemoglobin, mean corpuscular hemoglobin concentration, granulocyte and organs-body weight ratio. However, serum alanine transaminase activities, total proteins, direct bilirubins, Cl− concentrations and body weight gain were significantly (P Conclusions The extract caused selective changes in some biochemical parameters of organ function; however, since only mild alteration was observed at a dose of 300 mg/kg, the garlic bulb may be considered to be relatively safe and could be explored as an oral remedy at this dose.

TL;DR: The data suggest that some tin compounds may inhibit haematopoiesis, possibly by interfering with the intestinal absorption of iron, in rats fed on diets containing various salts or oxides of tin.
