The present studies were designed to investigate the morphology and stainability of the chicken spermatozoa. Semen samples were collected by abdominal massage from 10 cocks of Arbor, Acres strain (egg breed) and 10 cocks of white Cornish strain (meat breed). The semen samples were diluted with Sarker's solution and were washed. Some of the semen smear slides were stained with seven differential stain methods and was compared with one another by light microscope. In addition to the staining already compared, the length of heads, middle pieces and tails of 400 spermatozoa of two chicken breed was measured with micrometer. The results obtained from these, studies were as follows: 1. Eosin stain appeared to give good results than hematoxylin, pre-treated protease and eosin or hematoxylin stain, pre-treated protease and hematoxylin-eosin stain, carbol-fuchsin, stain and Giemsa 9 technique in differential staining of spermatozoal three portions and pre-treated protease and eosin stain appeared as good staining methods for middle piece of spermatozoa. 2. The average length of chicken spermatozoa was $90.4{\pm}4.0{\mu}m$, and the average length of the head, middle piece and tail of spermatozoa was $13.0{\pm}0.5{\mu}m$, $3.8{\pm}0.2{\mu}m$ and $73.6{\pm}3.8{\mu}m$ lesoectively. 3. The average length of spermatozoa of Arbor Acres strain was $89.2{\pm}5.0{\mu}m$ and the average length of the head, middle piece and tail of spermatozoa was $12.9{\pm}0.5{\mu}m$, $3.8{\pm}0.2{\mu}m$ and $72.5{\pm}4.7{\mu}m$ respectively. The average length of spermatozoa of with Cornish was $91.6{\pm}3.0{\mu}m$ and the average length of the head, middle piece and tail of spermatozoa was $13.1{\pm}0.5{\mu}m$, $3.8{\pm}0.2{\mu}m$ and $74.7{\pm}2.8{\mu}m$ respectively.

Several methods have been used in the detection of Helicobacter pylori (H. pylori) which was believed to be a pathogenic organism causing chronic gastritis, benign peptic ulcer, gastric carcinoma or malignant lymphoma. Even though several methods were introduced for detection of H. pylori in stomach, there were controversies in their sensitivities and specificities. This experiment were designed to study the comparative analysis of staining methods (hematoxylin and eosin (H&E), Giemsa, Warthin-Starry and immunohistochemical stain) to dectect H. pylori in the gastric mucosa. The results were as follows. Average density score of H. pylori classified by Genta were 2.29 in Warthin-Starry stain, 2.19 in Giemsa stain, 1.34 in immunohistochemical stain and 0.98 in H&E stain. By comparison between inflammatory degree by Sydney system and result of Warthin-Starry stain, the detection rate and densities of H. pylori were increased from mild (61.5% and 0.8), moderate (90.4 and 2.1), and severe (100% and 3.2). From the above findings, Warthin-Starry stain is useful method for detection of H. pylori in gastric mucosa.

The author observed histochemically the nature of the calcified tissue in the rabbit dental pulp, induced by pulpal injection of potassium permanganate. The pulp of rabbit mandibular incisors were exposed and enlarged by a dental hand reamer. The exposed pulps were injected with 0.05ml of 20mM solution of potassium permanganate dissolved in Ringer's solution in experimental tooth. Also the control tooth received a pulpal injection of 0.05ml of Ringer's solution. After pulpal injection, the tooth was plugged with a gutta-percha root canal point. The staining techniques were hematoxylin-eosin stain, van Gieson stain, PAS reaction, toluidine blue stain, alcian blue-hematoxylin stain and colloidal iron-picric acid stain. The results were as follows: 1. The pulp on experimental tooth showed osteodentin-like calcified tissue. Also, in some areas, false denticle-like substance were observed. 2. The central portion of the calcified matrix showed metachromasia in toluidine blue stain had strong staining capacity in alcian blue stain. 3. The peripheral portion of the calcified tissue revealed marked van Gieson positive reaction for collagen. But their staining ability in alcian blue was slight and metachromasia was not appeared.

This study investigated the degree of fracture healing using cathode stimulation of microcurrent, cathode and anode stimulation of High Voltage Pulsed Galvanic Current (HVPGC). Measures were performed by X-ray test and Hematoxylin-Eosin stain and Masson's trichrome stain and osteocalcin-positive immunoreactivity. In the measure of X-ray, microcurrent stimulation group revealed more rapid recovery than the groups of HVPGC's cathode and anode stimulation in bone union degrees. Microcurrent group showed significant difference statistically (p<0.05). However, the groups of HVPGC's cathode and anode stimulation didn't show significant difference statistically(p>0.05). In the histologic examination with Hematoxylin-Eosin and Masson's trichrome, microcurrent stimulation group was observed more proliferation of irregular woven bones than the groups of HVPGC's cathode and anode stimulation. Osteocalcin-positive immunoreactivity was observed more osteoblast, osteocyte, osteoclast, bone matrix than the groups of HVPGC's cathode and anode stimulation. Microcurrent stimulation can be considered an effective way during healing of fresh fracture and it can show more effective method than HVPGC's cathode and anode stimulation in the fracture healing.

Present study investigated the effect of Nuva-Lite irradiation on the labial oral mucosa of the albino rats. The specimens were embedded in paraffin wax and stained with histological and histochemical procedures such as hematoxylin-eosin stain, Feulgen reaction, methyl green-pyronin stain, alloxan Schiff reaction, -SH group reaction, PAS reaction, colloidal iron reaction and toluidine blue stain. The specimens 24 hours to 3 days after ultraviolet irradiation exhibited mild intracellular edema in the prickle cell layer. On 6th and 10th day after irradiation rete peg hyperplasia was prominent. Ultraviolet irradiation caused diminution of Feulgen reacted DNA. However, sulfhydril and ${\alpha}$-amino acid radicals were increased at the upper layer of stratified squamous epithelium after irradiation.

Acupuncture and herbal medicine have been used to prevent and treat the cerebrovascular accident, such as a stroke, and many studies of acupuncture and moxibustion concerning to the stroke have been undertaken in the human and various animals. However, it was not published the protective effect of the electroacupuncture (EA) of Huan-do (GB30) on the transient forebrain ischemia injury. The neuroprotective effects of EA (2 ms, 10 Hz, and 1 - 2 mA) of GB30 on the transient forebrain ischemia injury was investigated by western blot of nNOS and hematoxylin and eosin stain in Sprague-Dawley rats. The transient forebrain ischemia injury resulted in increased expression of nNOS in the brain for 6 hrs after ischemia, and EA decreased significantly expression of nNOS protein in brain increased by transient forebrain ischemia injury. The survived neuronal cell stained with hematoxylin and eosin (H&E) decreased in the hippocampus by the 7 days after ischemia comparing with the normal. Comparing with the normal, the survived neurons seriously decreased cell in the hippocampus after the injury. However, the proportion of survived neurons was increased in EA treatment. These results suggest that EA of GB30 have neuroprotective effects on transient forebrain ischemia injury.

In this study we examined the effects of water extract of garlic on carbon tetrachloride-induced liver injury, and demonstrated increased beneficial enzyme and anti-oxidant activity as well as histopathological changes (by Hematoxylin-Eosin (H&E) staining, Trichrome staining, and TEM examination), and showed that the treatment was dose-dependent and safe. A total of 42 male Sprague-Dawley rats were divided equally (n=7) into six groups. To induce hepatotoxicity in these subjects, carbon tetrachloride diluted in an equal volume of olive oil was intraperitoneally administrated at 0.5 ml/kg (0.20 g/kg/day) once a day for five days. Water extract of Korean-grown garlic was administered via a stomach sonde once a day, 5 days a week, for a total of 4 weeks. Groups received 0.35 g/kg (E1), 0.70 g/kg (E2), or 1.40 g/kg (E3), with the dose adjusted for body weight. Administration of garlic extract resulted in positive physiological effects in terms of reduced oxidative stress and toxicity, and induced functional changes in the liver. Comparing the subject groups (E1, E2, E3) administered different doses of garlic extract, the importance of morphological analysis in further studies is emphasized, because morphological changes indicating hepatotoxicity could occur, even though beneficial enzyme activities were found to be elevated.

Objective : The aim of this study is to investigate the inhibitory effect of Injinchunggantang on hepatic sclerosis induced by $CCl_4$. Methods : Weight, liver function test and complete blood cell count, gross findings, and findings on liver tissue of the past(Hematoxylin & Eosin stain, Masson-Trichrome stain) were studied. Results : When it comes to the change of rats' body weight, The $CCl_{4^+}$Injinchunggantang group lost far less weight than The $CCl_{4^-}$only group. In the liver function test, which is focused on various areas such as total cholesterol, alkaline phosphotase, albumin, aspartate transaminase, alanine transaminase, The $CCl_{4^+}$Injinchunggantang group was much more closer to normal limit than the $CCl_4$ only group. In the complete blood cell count, including white blood cell, red blood cell, hemoglobin, hematocrite, platelet, The $CCl_{4^+}$Injinchunggantang group significantly closer to normal limit than $CCl_{4^-}$only group. In the gross findings of hepatic fibrosis models, Injinchunggantang showed inhibitory effect on hepatic fibrosis in the order. In the past findings of hepatic fibrosis models in Hematoxylin & Eosin, Masson-Trichrome staining, the liver in $CCl_{4^-}$only group showed atrophy and necrotic change with white nodules, whereas that of $CCl_{4^+}$Injinchunggantang group showed lesser significant change with the well_preserved tone of the tissue. In the extent of the inhibition of the hepatic fibrosis, the Injinchunggantang group showed statistically significant inhibitory effect(p<0.05) in the sclerosis model. Conclusions : These results show that Injinchunggantang have inhibitory effect on hepatic sclerosis induced by $CCl_4$ and further ultimately prevent liver cirrhosis. To obtain more credible results in this experiment, the invention of a new experimental model more similar to human hepatic sclerosis is still needed.
