JOURNAL FREE ACCESSThe present study concerns the coloration of various peroxidase reagentswhen mixed with enzymes and nonenzymatic substances in the test tube. The followingresults and conclusions were obtained. 1) Human myeloperoxidase showedalmost the same results as for horseradish peroxidase. 2) Catalase reacted onlywith paraphenylenediamine-hydrogen peroxide solution. 3) Cytochrome c reactedmore intensely with leuco-patent blue-hydrogen peroxide than with any of theother reagents tested. 4) Nonenzymatic substances such as copper sulphate andosmium tetroxide were strongly reactive with peroxidase reagents. In other words,a positive reaction by histochemical technique using so-called peroxidase reagentsis not due only to hemoproteins.View full abstractDownload PDF (715K) -

JOURNAL FREE ACCESSFifty-two forearms of 26 Japanese adult cadavers were examined. The flexor digitorum superficialis can be separated into two layers: a superficial layer and a deep layer. The superficial layer is composed of the radial head and the superficial part of the humeroulnar head. It forms two muscle bellies which give rise to the tendons for the third and fourth digits, respectively. The deep layer is composed of the deep part of the humeroulnar head. After forming an intermediate tendon, the deep layer also divides into two fleshy bellies which give rise to the tendons for the second and fifth digits, respectively. Based on the mode of occurrence of the communicating muscle fasciculi between the superficial layer and the deep layer, the flexor digitorum superficialis can be classified into four types.
Type I muscle has no communicating fasciculus (4/52,7.7%).
Type II muscle has a communicating muscle fasciculus between the intermediate tendon and the muscle belly for the fourth digit (muscle fasciculus A) (29/52,55.8%).
Type III muscle has the muscle fasciculus A as well as another communicating muscle fasciculus between the intermediate tendon and the belly for the third digit (muscle fasciculus B) (18/52,34.6%).
Type IV muscle has the muscle fasciculus B only (1/52,1.9%).
Six other kinds of variations were also recognized.
The flexor digitorum superficialis is innervated by four to five branches from the median nerve. These are usually grouped into uppermost, middle and distal branches. In one case, a small part of the humeroulnar head was innervated by a slender branch from the ulnar nerve.View full abstractDownload PDF (1716K) -

JOURNAL FREE ACCESSNigral projections to the inferior colliculus were examined in the rat, using the HRP method. After HRP injections into the inferior colliculus, labeled cells were found mainly in the pars lateralis of the substantia nigra but a few were present in the contralateral pars lateralis. These cells were found abundantly in the posterior portion of the pars lateralis and to some extent in the anterior portion of this structure. When HRP was injected into the superior colliculus, HRPmarked neurons were found mainly in the pars reticulata together with a few in the anterior portion of the pars lateralis.View full abstractDownload PDF (1121K) -

JOURNAL FREE ACCESSUnder the light microscope, the thyroid follicles of young germfree rats were found to be large in size and lined with flattened epithelial cells. Electron microscopy revealed that the thyroid follicular cells in these animals were provided with less prominent organelles such as the Golgi apparatus, lysosomal dense bodies and rough surfaced endoplasmic reticulum, compared to those in their conventional counterparts. Cholesterol feeding tended to lead to an increase in large colloid droplets in the apical cytoplasm and lipid droplets in the basal cytoplasm of young germfree rats. The above results provide morphological evidence for a low activity of thyroidal secretion in the young germfree rat.View full abstractDownload PDF (2655K) -

JOURNAL FREE ACCESSThe mouse tongue musculature and its movements were studied macroscopically. The attachment of the extrinsic tongue muscles was also ascertained by dissection and light microscopy.
1. The genioglossus muscle of the mouse was attached to the posterior surface of the midsagittal region of the mandibular symphysis but medial and posterior to the geniohyoid tendon.
2. The genioglossus muscle was divided into three parts. Its anterior border was not straight and did not coincide with that of the intermolar eminence. This means that as in animals without an intermolar eminence, the anterior border of the genioglossus does not always coincide with an intermolar eminence.
3. On closing or opening of the mouth, the tongue shape changed in the dorsum linguae, showing an intimate relationship with the genioglossus muscle, but the position of the geniohyoid muscle remained almost static.View full abstractDownload PDF (1219K) -

JOURNAL FREE ACCESSAn anomalous case of the right subclavian artery arising from the aortic arch as the last branch, of which the first branch was the bicarotid trunk and the second the left subclavian artery, was found in a 73 year old female among cadavers for student dissection in 1978. This case belonged to type H of Adachi-Williams-Nakagawa's classification. In addition, the right recurrent laryngeal nerve was not found but there were minor variations in the azygos venous system. Based on a reexamination of many original reports concerning such variations, a table was prepared.View full abstractDownload PDF (2061K)
