JOURNAL FREE ACCESSElectron microscopic studies were made of the parathyroid gland of quail aged 4 to 12 months. Most parenchymal cells consisted of chief cells. Sometimes, cells having numerous microfilaments, scant granular endoplasmic reticulum, a few mitochondria, a small Golgi apparatus, and long cell processes that extended between contiguous cells were located on a basal lamina. These cells may serve as supporting cells rather than as secreting cells. Numerous free ribosomes, abundant mitochondria, a well-developed granular endoplasmic reticulum and Golgi apparatus, many prosecretory granules and lysosomes, and a few mature secretory granules were characteristic of the chief cells. The cisternae of the Golgi apparatus were arranged in circular and serpiginous profiles in some chief cells. Secretory granules were distributed randomly throughout the cytoplasm and near the plasma membrane. Some cisternae of the granular endoplasmic reticulum occurred in close proximity to mitochondria. Morphological evidence for the synthetic and secretory activities of the chief cells suggested an active parathyroid function.View full abstractDownload PDF (5280K) -

JOURNAL FREE ACCESSThe origin and ramification of the posterior deep temporal artery of the dog have been studied by means of the acryl plastic injection method. The artery arose distal to the origin of the inferior alveolar in more than half of all the examples observed, but in common or in contact with the inferior alveolar in others.
All the branches of the artery were mentioned; the lingual, the temporomandibular joint, the anterior, the lateral pterygoid muscular branches and the masseteric artery. Then the artery terminated into the superior, the superoposterior and the posterior branches.View full abstractDownload PDF (2979K) -

JOURNAL FREE ACCESSImmunohistochemical localization of estrone (E1) and progesterone (P)in porcine ovary and human placenta has been demonstrated by direct and indirect antibody techniques. E1-bovine serum albumin (BSA) and P-BSA conjugates have been used for the immunization of rabbits. The antisera obtained were titrated by the passive hemagglutination test (E1: 1: 655,360, P: 1: 327,680) and radioimmunoassay measurement ability of various dilutions of antisera (E1: 1: 30,000, P: 1: 40,000). The anti-steroid properties of the sera indicated that they were specific for each S-P conjugate, and“link-antibody”was formed between the antigen and BSA as revealed by the immunodiffusion technique due to the precipitin line observed using the BSA-absorbed antiserum. In the Graafian follicle, both steroids have been demonstrated within round or oval single cells of the theca interna, although the intensity of the reaction was higher with the E1 immunity, and correlated with the localization of sudanophilia, G-6-PDH,3β-ol SDH, and lysosomal enzymes. The cells appeared to be theca gland cells. A similar reaction was observed in the majority of the interstitial cells including the hilar cells. Some groups of these, however, exhibited distinct granular and orange colored autofluorescence, and showed contours of macrophages that had engulfed steroid producing cells. In the corpora lutea, the same steroids were found in the theca-lutein cells. The granulo-lutein cells had no antigenicity to E1, but showed a very weak immuno-positive reaction to P, moderate sudanophilia, and strong activities of G-6-PDH and 3β-ol SDH. The atretic follicles and interstitial glands were immuno-positive to E1. In human placenta at term, E1and P were localized at the syncytiotrophoblast layer, although the Langhans cell region was not identified. However, a distinct and unequivocal identification between the two steroids investigated was not possible.View full abstractDownload PDF (4731K) -
Functional Anatomy of the Olfactory Organ in the Fresh Water Teleost, Heteropneustes Fossilis (BL. )HEM RAJ GOEL1978 Volume 55 Issue 5 Pages 289-299

JOURNAL FREE ACCESSThe anatomical and histological studies of the olfactory organ of the fresh water fish-H. fossilis, were performed in the adult specimens. The olfactory chambers are paired, situated antero-dorsally on either side of the middle line of snout. Each olfactory chamber communicates outside by an anterior and a posterior nasal openings. The anterior opening is tubular while the posterior is simple and oval. The accessory nasal sac is absent but the median raphe is present. Each lamella bears a linguiform process.
The epithelium of the olfactory lamella comprises supporting, olfactory receptor (primary and secondary neurons), basal and goblet cells. Synapses are formed between the primary and secondary neurons. Basal cells differentiate into the olfactory receptor cells and the supporting cells. Goblet cells are mainly present on the free margin of the epithelium.View full abstractDownload PDF (1892K)
