Rat Submandibular Gland

The present study investigated the size, number, and distribution of microperoxisomes (MP) during the prenatal and postnatal development of the rat submandibular gland (SMG). A three-fold increase in MP number per cell was observed in the cells of the rudiment from the 15th to the 16th day of gestation. The early secretory and striated duct cells contained about 9.0 MP. The number of MP per secretory cell decreased such that 3.5 MP were found in each mature acinar cell. In the striated duct cells, MP number progressively increased to 40.0. As the convoluted granular tubule cells (CGT) developed from striated duct cells there was an increase in MP number from 16.0 to 26.0/cell. At maturity, the convoluted granular tubule cells contained only 14.0 MP. Throughout development of the SMG, intercalated duct cells showed only rare MP. The data suggests that the number, size, and distribution of MP changes as a function of the particular path of differentiation followed by the various cells in the rat SMG.

The present study was designed to investigate 1) whether parasympathetic reflex vasodilatation occurs in the submandibular gland (SMG) in deeply urethan-anesthetized, cervically vagotomized, and sympathectomized rats when the central cut end of the lingual nerve (LN) is electrically stimulated and 2) to what extent the neural mechanisms underlying such responses are the same as those involved in the response to direct stimulation of the chorda-LN (CLN). Stimulation of each nerve separately elicited a marked blood flow increase in SMG. Section of the chorda tympani abolished the SMG blood flow response but had no effect on the lip blood flow increase evoked by LN stimulation. Section of the CLN abolished the SMG blood flow increases evoked by stimulation of either nerve. The SMG blood flow increases (regardless of whether they were evoked by LN or CLN stimulation) were markedly reduced by the autonomic cholinergic ganglion blocker hexamethonium. The present study demonstrates that a parasympathetic reflex vasodilator mechanism is present in the rat SMG and that it can express its effects under deep general anesthesia.

Oxygen consumption of slices of rat submandibular gland was monitored with an oxygen electrode method. Carbachol stimulated an immediate increase in tissue respiration that was inhibitable by ouabain. The stimulation required the presence of calcium in the incubation medium and was blocked by atropine. The calcium ionophore A23187 also stimulated ouabain-sensitive oxygen consumption in the tissue slices. The results show that the mechanism using the extra energy during cholinergic stimulation is the sodium pump. Amiloride at a 1, 10, or 100 microM concentration had no effect on stimulation of ouabain-sensitive respiration by carbachol. Since amiloride, which is known to block the sodium reabsorption process in the ductal segment, has no effect on the stimulation, the increased sodium pump activity is probably located in the acinar region and is associated with the primary fluid secretion process.
