Regeneration fo the completely excised gastrocnemius muscle in the frog and rat from minced muscle fragments.
In 85 frogs and 29 rats, the entire gastrocnemius muscle was removed. After removal of as much connective tissue as possible, about two-thirds of the remaining muscle was finely minced with a scissors. These minced fragments were orthotopically re-implanted, and the overlying skin was sutured. As the implanted muscle fragments degenerate, new muscle fibers appears in the regenerate. The proport...
متن کاملPURIFICATION AND PROPERTIES OF RAT GASTROCNEMIUS MUSCLE N-ACETYL-I3-DGLUCOSAMINIDASE A AND B.
N-acetyl-B-D-Glucosaminidase was purified by affinity and ionexchange chromatography. Two major, A and B, and three minor intermediate forms were isolated and characterized. NAG-A and NAG-B were purified 440 and 1200 fold with final yields of 16 and 23 percent respectively. Each activity was represented by a single protein band. After 70 min preincubation at 55°C a loss of70% activity of N...

Background The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. MaterialsAndMethods This self-controlled study was performed on 24 adult females. Blood sampling was performed during Ramadan and two months l...
متن کاملMouse gastrocnemius muscle regeneration after mechanical or cardiotoxin injury.
The goal of our study was to compare the skeletal muscle regeneration induced by two types of injury: either crushing, that causes muscle degeneration as a result of mechanical devastation of myofibers, or the injection of a cardiotoxin that is a myotoxic agent causing myolysis of myofibers leading to muscle degeneration. Regenerating muscles were analyzed at selected intervals, until the 14th ...
متن کاملElectrophysiologic assessment of sciatic nerve regeneration in the rat: surrounding limb muscles feature strongly in recordings from the gastrocnemius muscle.
Striking inconsistencies between the results of morphometric and electrophysiologic examinations of the regenerating nerve were observed in a previous study featuring the bridging of a 14 mm gap in the rat sciatic nerve. To shed light on this dichotomy, seven further rats were subjected to permanent sciatic nerve transection and assessed electrophysiologically, histologically and by retrograde ...
