- beta,beta'-Iminodipropionitrile toxicity in normal and congenitally neurofilament-deficient Japanese quails.
- Mitsuishi K1, Takahashi A, Mizutani M, Ochiai K, Itakura C.Author information 1Department of Comparative Pathology, Faculty of Veterinary Medicine, Hokkaido University, Sapporo, Japan.AbstractMorphological effects of a neurotoxin, beta,beta'-iminodipropionitrile (IDPN) were analyzed in normal and congenitally neurofilament (NF)-deficient Japanese quails. These quails (6 weeks old) were injected intraperitoneally with IDPN (0.2 g/kg body weight) three times every 3 days. They were necropsied at 10 to 12 days after the first injection. In normal quails, axonal swellings were observed histologically in the ventral motoneurons, ventral root, commissura grisea and spinal ganglion in the cervical and synsacral spinal cord. Electron microscopically, the changes consisted of increased NFs, with scattered mitochondria, smooth endoplasmic reticulum and microtubules. The myelin sheaths of the involved nerves were thinner than those of the normal axons. These lesions were similar to those induced by IDPN intoxication in mammalian experimental animals. In NF-deficient quails injected with IDPN, no axonal changes were detected. These findings suggested that IDPN selectively attacked the NFs.

- Participation of emotional structures of the brain in the regulation of gastric secretory function.
- Kassil' VG, Butkevich IP, Mikhailenko VA.AbstractThe influence of the self-stimulation (SS) positive-reinforcement zones of the brain on the secretion of gastric juice was investigated using eight adult dogs with gastric fistulas. An intracerebral-S3 instrumental response was developed after implanting concentric (bipolar) electrodes into various zones of the reward system (hypothalamus, mammillary bodies, ventral thalamic nucleus, commissura grisea media, internal capsule, nucleus of the stria terminalis, and the crus cerebri). A normal acidity of the stomach contents was found in five dogs after surgery during the interdigestive period and a sharply elevated acidity in three dogs. A large quantity of thick foamy mucus and a turbid juice was secreted 3-5 min after the onset of SS. Self-stimulation did not alter the pH of the stomach contents in dogs with an initially normal pH, while it normalized this parameter in dogs with an initially elevated acidity. Bilateral supradiaphragmatic vagotomy in the animals of the latter group shifted the pH in the alkaline direction; however, the pH was completely normalized only as a result of intracerebral SS. Thus, positive emotional excitation associated with the stimulation of various reward zones normalized the acidity of the stomach contents; moreover, this response was not associated with the efferent systems of the vagus nerves.

- The median and lateral substantia gelatinosa in the cervical cord of the musk shrew (Suncus murinus) and its synaptic composition.
- Sugiura Y, Kitoh J.AbstractThe extent and laminar arrangement of the substantia gelatinosa (SG) were examined in the cervical spinal cord of the shrew. Between C1 and C6 or C7 the three dorsal layers on either side of the gray matter were confluent at the commissura posterior grisea in shrews of both sexes. Lamina I was thin with no large marginal cells. Lamina II comprised the major part of the SG, consisting of outer cellular and inner neuropil layers. Lamina III was composed of a meshwork of axon terminals, dendritic profiles and myelinated fibers. Unlike the situation in other mammals, in shrew the incidence of axon terminals with round vesicles was similar in the three uppermost layers, but the occurrence of terminal profiles with flat vesicles was significantly greater in deeper laminae. Lamina IV was restricted to the dorsal horn and did not extend through the midline.
