Sialolithiasis of the Submandibular Gland: Report of Cases.

Sialolithiasis is the formation of calcific concretions within the parenchyma or ductal system of the major or minor salivary glands, but it most commonly affects the submandibular salivary gland. Sialolithiasis usually occurs in adults aged 30 to 60 years and causes pathognomonic pain during meals. The treatment of sialolithiasis depends on the size and location of the calculi.

Cardiac and intestinal contractions under the influence of triturated drug dilutions.

Triturated dilutions of acetylcholine and adrenaline are found to produce reverse effects than their parent one on the mechanical performance of mammalian heart and intestine in vitro. However, there is a variation in the magnitude of reverse response observed for both the tissues. It is concluded that variation in the effect of triturated dilutions is probably due to handling and shaking of the diluted drug before use in experiments.

Effect of short term immobilization on mechanical characteristics of skeletal muscle in uromastix.

Gastrocnemius muscles of Uromastix were used to observe the effects of short term (7 days) immobilization in flexed position. Results demonstrated significantly (P < 0.01) lesser magnitude as well as rate of rise in isometric twitch and tetanic tensions with insignificantly different twitch/tetanus ratio in the immobilized muscles.

Mechanical response of lizard skeletal muscles to disuse: II. Effect of short-term denervation.

The gastrocnemius muscles of Uromastix hardwickii were used to determine the effects of the absence of neural influence on them. For this purpose, the muscles were denervated for 7 days and were used to record isometric twitch and tetanus. The contraction parameters thus obtained from the denervated muscles were then compared with their own controls.

Mechanical response of lizard skeletal muscles to disuse: I. Effect of short-term tenotomization.

The gastrocnemius muscles of the reptile, Uromastix hardwickii were tenotomized for seven days according to the method described earlier and their mechanical responses were recorded to study the effect of cessation of proprioceptive impulses on the functioning of these muscles. The parameters measured were isometric twitch and tetanic tensions, time dependent tension parameters and other time dependent parameters of twitch and tetanus records. The isometric twitch and tetanic tensions, their ratios and the rate of rise in twitch and tetanus along with P/ms were found significantly lesser in the tenotomized muscles.
