  • A number of experimental studies have been carried out in order to clarify the question as to how temporomandibular joint adapt to the changes of mandibular movement and occlusal equilibration. Recently, the studies on the interrelations between anatomical structure of temporomandibular joint and the state of occlusion have been actively performed in dentistry particularly in prosthodontic field. Author performed extraction of unilateral mandibular molars in 30 mature male rats, and observed histological changes of temporomandibular joint through the light microscope. Following results were obtained. 1. The loss of unilateral teeth gave rise to the changes in the location of condylar head, that is, interior displacement of condylar head in the extraction side and upper displacement in the non-extraction side. 2. Articular disk was compressed by the interior surface of condylar head, resulting in its extension below the condylar neck in the extraction side, and the histological arrangement of the compressed area showed irregular feature. 3. The extension of articular disk below the condylar neck was accompanied with the contraction of muscle fibers which were originated from the articular disk. 4. The cartilage layer of articular fossa to the exterior of the extraction side showed hypertropy. 5. Early in the experiment, the inernal extremity of condylar head of extract ion side showed bone resorption, and cartilage layer of condylar head showed hypertropy. At 12 weeks after experiment, the condylar surface showed flattened, and the cartilage layer of condylar head was replaced by the compact bone. 6. The articular disk showed the formation of pannus in the extraction side as well as in the non-extraction side. 7. The occlusal disturbance due to unilateral missing teeth has brought about the non-inflammatory retrogressive change and osteoarthrotic change late in the experiment.

  • Since the fact was known that mouth breathing resulted from the adenoid hypertropy causes malocclusion, many investigators have studied nasopharynx and adenoid in order to clarify the role in relation to the effect on face and occlustion and the development of airway. The author analyzed 13 items in longitudinal cephalometric roentgenograms of 17 boys and 19 girls taken from the age of 7 to 12. The results were as follows. 1. The means and standard deviation for the measured items were obtained. 2. The continual growth of nasopharyngeal cavity was more affected by the height than the depth. 3. The size of adenoid was larger in males than in females, especially on R, $D-AD_2$. 4. Airway percentage was highest in boys at age 10 and girls at age 9. 5. The items showed significant differentiation between males and females were airway percentage, posterior height, $D-AD_1,\;D-AD_2$, and R.

  • Lamerin breed of the silkworm Bombyx mori L. is the only mulberry silkworm breed which survives with an associated microsporidian $(Lb_{ms})$ infection from generations. This present comparative investigation has produced information on the influence of $Lb_{ms}$ on the growth and development of the breed. The $Lb_{ms}$ transmits tranovarially as well as perorally at low level. Larvae developed from the eggs laid by female, infected with $Lb_{ms}$ were as normal as larvae developed from the eggs laid by healthy female. In infected tissues early developmental stages and mature spores located intracellularly but did not show hypertrophy of cells of the host. The meronts and sporonts measures $0.46{\pm}0.25,\;1.11{\pm}0.05{\mu}m$ in length and $0.32{\pm}0.05,\;0.78{\pm}0.10{\mu}m$ in width respectively. The mature spore measures $4.36{\pm}0.06{\mu}m$ in length and $2.14{\pm}0.01{\mu}m$ in width.

  • Feeding rats a diet containing bean-hull causes hypertropy in their parotid glands due to the high tannin content. The amount of feedintake of rats led bean-hull was higher than that of rats fed a standard diet. However, the increase in body weight of rats fed bean-hull was lower than that of rats fed a standard diet, which resulted in significantly low feed efficiency of the bean-hull containing diet. Within one week, parotid glands significantly enlarged and a series of proline-rich proteins (PRPs) were produced, which were similar to those induced by feeding high-tannin sorghum with flight differences in molecular weights. Even though the direct comparison between PRPs produced by the bean-hull containing diet and those induced by the high sorghum diet is not appropriate due to laboratory inconsistences, several new PRPs were produced by high tannin diets in both experiments. Differences in molecular weights of PRPs induced in two different tannin sources must be funker investigated to be fully characterized. These morphological and biochemical changes have now been demonstrated to occur in response to the ingestion of tannins, presumably to diminish the anti-nutritional effects of tannins.

  • Background and Objectives : Gastric acid reflux has been suggested to have an association with sleep apnea(SA). This study's aim is to evaluate the relationship between reflux laryngitis and SA through the fact that the treatment of reflux laryngitis may impact the snoring and SA related symptoms in selective individuals. Methods : Population consist of 24 males and 10 female aged 34 to 66 years(mean age 50 years) confirmed by Reflux Finding Score(RFS) of PC Belafsky. Thirty four patients with reflux laryngitis and associated symptoms of SA were treated with proton pump inhibitor(Rabeprazole sodium 10mg/day) for 60 days. The degree of snoring and apnea related symptoms were evaluated using questionnaires, and palatine tonsillar hypertropy(PTH) and RFS were compared preoperatively and postoperatively. Results : After antireflux treatment for 60 days, the snoring(p=0.039), daytime sleepiness(p=0.002), and concentration(p=0.011) were significantly improved(p<0.05) and RFS was significantly decreased(p=0.000), but morning headache(p=0.057) and sleep apnea(p=0.083) were not significantly improved(p>0.05) and PTH was not significantly decreased(p=0.328). Conclusion : Treatment of reflux laryngitis significantly impacted the snoring, daytime sleepiness, and concentration in selective individuals. These results suggest some close relationship between reflux laryngitis and SA, and the treatment of reflux laryngitis may be some effective in those with both disorders.

  • Histopathological changes in gills by potassium permanganate were investigated in four fish species. flounder(Pararychthys olivaceus) and rockfish(Sebastes schlegeli) in marine fish, and carp(Cyprinus carpio) and eel(Anguilla japonica) in freshwater fish. Marine fishies were more sensitive to $KMnO_4$ than freshwater fishies and have shown histological changes even in low concentration of 1ppm. Eels were less affected than carp in high concentration of $KMnO_4$. Especially in eels, hyperplasia and hypertropy of mucus cells were observed. Compared to in underground water. the effect of KMnO₄ were reduced very much in pond water. That this differences were due to the concentration of organic substances were certained by experiment with various feed concentrations. The potency of $KMnO_4$ were influenced by dissolved oxygen.

  • A 27 years old male developed right-sided massive, recurrent, pleural transudate. EKG and echocardiogram showed right ventricular hypertropy. Chest X-ray and concurrent perfusion lung scan, performed after enough expansion of the right lung by drainage of the effusion through small cathter, showed that perfusion defect mismatched with the roentgenographic defect, which was likely to be a high probability of pulmonary thromboembolism. By cardiac catherization and pulmonary angiography the occlusion of pulmonary veins drained from the upper and middle lobe of the right lung could be revealed. More precise cause of occlusion couldn't be clear up because thoracotomy had to have been dangerous due to severe pulmonary hypertension. So the massive reurrent effusion was treated by repeated tetracycline instilations through chest tube and he was discharged. After following up 14 months at out-patient clinic, he expired because of sudden massive hemoptysis.

  • Objective : UV irradiatiion causes skin-aging involving coarse wrinkles, thickning, dyspigmentation, and rough skin surface. This study was aimed to elucidate the anti-winkle activity of complex diet of Korean red ginseng (RG) and fish oil (FO) on UV-induced Photoaging. Methods : To investigated photo-protective effects of Korean red ginseng and fish oil on UV-induced damaged skins, SKH hairless female mice were randomly divided into six groups [control, UV, UV/RG, UV/FO, UV/RG/FO(low), UV/RG/FO(high)]and orally administered three times a week respectively. UV radiation was applied to the backs of the mice three times a week for 8 weeks. Expressions of matrix metalloproteinase (MMP)-3, MMP-13 and tissue inhibitor matrix metalloproteinase (TIMP)-1 in skin were measured by immunohistochemical staining. Results : In this study, UVB-induced epidermal hypertropy was diminished by RG group or FO group or complex group of RG and FO. Expression levels of MMP-3 and MMP-13 were reduced and expression level of TIMP-1 was increased by RG group or FO group or complex group of RG and FO. Especially MMP-3 and MMP-13 were markedly reduced by diet of FO and complex diet of RG and FO compared with untreated group. Conclusions : This results suggest that complex diet of RG and FO have a anti-wrinkle activity on UV-induced photo-aging and intrinsic aging.
