Objectives : This study aimed to suggest distinct signs of Greater yin disease (tàiyīnbìng, 太陰病) by researching the etymology of three terms: zi-tong (自痛), jie-ying (結硬), and yin-er (因爾), which are exclusive found only in Greater yin disease (太陰病) in Gangpyeong-shanghanlun, but not in other categories. Methods : We studied the etymologies of the three terms that are unique in Greater yin disease, then found some pathological signs that are related with them through the four mental illness cases, which include somatization, obsessive-compulsive behavior, delusion, and panic disorder. Results : Based on the definitions of each term, we diagnosed the four patients who had mental illnesses as having Greater yin disease, and we observed meaningful improvements after administering herbal medication. After Gyejigajakyak-tang administration, the Insomnia Severity Index (ISI) score decreased from 18 to 7 and the Beck's Anxiety Index (BAI) score decreased from 36 to 18 in the first case, the ISI score decreased from 27 to 16 and the BAI score decreased from 50 to 33 in the second case, and the ISI score decreased from 23 to 4 and the BAI score decreased from 34 to 5 in the third case. In the last case, the ISI and BAI scores were 16 and 22, respectively, at the first visit, and it was found that the scores had changed to 6 and 22, respectively, at the last visit. Conclusions : We found that the unique terms in Greater yin disease, including zi-tong (自痛), jie-ying (結硬), and yin-er (因爾), can be interpreted as groundless arbitrary assumption, resting strong tension, and psychological projection based on the etymological hypothesis. Therefore, we suggest these as specific signs of Greater yin disease.

A 3-year-old female Connemara pony was referred to Jeju National University Equine Hospital because of weight loss and prolonged anorexia. On admission, heart and respiratory rates were slightly elevated while body temperature was within the normal range. The color of the conjunctival and oral mucosa was yellowish pink. The blood chemistry results showed that total bilirubin, aspartate aminotransferase, and gamma-glutamyl transferase levels were remarkably elevated while blood urea nitrogen was within the reference range. Transcutaneous abdominal ultrasound revealed an enlarged right lobe of the liver with prominently increased parenchymal echogenicity, reduced hepatic vessels, and rounded caudal border. The pony was tentatively diagnosed with chronic hepatitis and icterus; rest and supportive treatments were provided. Clinical signs aggravated on day 2 with hind quarter paresis and cranial nerve signs such as circling, drooping, jerking, and head pressing against walls. Recumbency and generalized ataxia (grade 5/5) were shown on day 3. Plasma ammonia concentration on day 3 was as high as 656 µmol/L. Necropsy and histopathologic examinations strongly supported a diagnosis of hepatic encephalopathy. This case of hepatic encephalopathy exhibited rapid progress from low to terminal grade within 4 days in a Connemara pony. The results provide well-established clinical and pathological data for future application.

Stachys sieboldii Miq. (SSM) and Acorus gramineus Soland. (AGS) have been used as traditional medicines for thousands of years in parts of Asia, including Korea, China, and Japan. Recent researches on SSM and AGS have documented a wide spectrum of therapeutic properties, including anti-inflammatory, anti-oxidative, neurodegenerative disease effects. However, the toxicity and safety of SSM and AGS, and their mixture (medicinal herber mixture, MHMIX) were not confirmed. Therefore, this study was performed to evaluate the acute toxicity and safety of SSM, AGS and MHMIX. SSM, AGS and MHMIX were orally administered at a dose of 5,000 mg/kg in ICR mice. Animals were monitored for the mortality and changes in the body weight, clinical signs and gross observation during the 14 days after dosing, upon necropsy. We also measured parameters of organ weight, clinical chemistry, and hematology. No dead and no clinical signs were found during the experiment period after administration of a single oral dose of SSM, AGS and MHMIX. There were no adverse effects on clinical signs, body weight, or organ weight and no gross pathological findings in any treatment group. Therefore, LD50 value of SSM, AGS and MHMIX may be over 5,000 mg/kg and it may have no side toxic effect to ICR mice. The results on the single-dose toxicity of SSM, AGS and MHMIX indicate that it is not possible to reach oral dose levels related to death or dose levels with any harmful side effects.

The causes of disease as well as the mechanisms that result in the presenting signs and symptoms of patients are basic elements in oriental medicine. The location of the disease is the region on which the cause and the nature of the disease acts. Syndrome reflects the cause of the disease and the pathological change and the location of the disease. It is customary to classify the location of the disease into two major categories. First is based on the exterior and interior and the second is based on the five internal organs. Exterior syndrome is caused by the invasion of exopathogen in skin and hair, channels and collaterals. Interior syndrome refers to the syndrome located deeply in the interior of the body such as five internal organs. The location of the disease is very important to distinguish different syndromes in the diagnosis and the treatment of a disease.

The Three months subacute toxicity of water soluble dimethyl dimethoxy biphenylate derivative (DDB-S), newly formulated therapeutic agent for hepatitis, was invesgated in SD rats. The body weight and clinical signs were observed after intravenous injection of DDBs at doses of 57, 75 and 100 mg/kg/day for three months. Decrease in motor activity and tremor were observed above 75mg/kg treated groups. Statistically significant changes at serum biochemical analysis were found in some group, how-ever, those changes were within the normal range and had no relationship with dosage. There was no abnormal morphological and pathological findings in relation to DDB-S treatment. The no observable adverse effect level of DDB-S in rats was estimated to be 57 mg/kg/day in this study.

A toxoplasmic uveitis case was reported on the focus of impairment of pathological findings and serological antibody titers after chemotherapy. A chief complaint of a 60-year-old male was a decreased and blurred vision in his right eye for 2 weeks after experiencing tremendous stress and fatigue. A steroid therapy for 3 weeks was not effective and the retinal lesion became necrotic. Anti-Toxoplasma gondii antibody titer was checked to be a strong positive by both ELISA and indirect latex agglutination assay (lLA). He was treated with Fansidar F for 8 weeks. His vision improved as the necrotic lesion healed by scarring, but the antibody titers still remained very high without any signs of negative conversion. It is suggested to be a recurrent case of the past asymptomatic infection by presumed immune suppression caused by excessive stress.

Traumatic injuries of the face often involve root fractures especially in anterior teeth. The prognosis and the treatment of the root fracture depend on the extent of the fracture line, general health and patient compliance. This case report outlines a new conservative trial treatment modality to stabilize the maxillary central incisors with horizontal root fracture on the cervical to middle third by fabricating canine guidance to remove loading on the traumatized maxillary central incisors during eccentric movements and thus inducing spontaneous healing of the fractured line between the fragments. Radiographs after thirty months showed adequate healing with no signs of pathological changes including root resorption, ankylosis or displacement. Long term follow-up revealed that vitality, stability and aesthetics were maintained and the patient was satisfied with the outcome.

Daily oral administration to Sprague Dawly rats for 4 weeks of DWP-301, at doses of 0, 500, 1000, 2000 mg/kg presented following results; 1) No animals died and there were no significant differences in general signs, body weight, food consumption, urinalysis haematological, biochemical, gross pathological and histopathological examination between control and treated rats. 2) Water consumption, pH-, protein- urobilinogen-, ketone-values in urine were significantly increased in the treated male and female rats. It is supposed that these differences in animals are a consistent feature of repeated overdosage with test suspensions. The results indicate that the non toxic dose of test compounds in rats is over 2000 mg/kg in this test system.

Acute toxicities of DWH-01 (Ranitidine : Bismuth : Sucralfate= 1.5: 2 : 6) were investigated in Sprague-Dawley rats. Seven days after oral administration of DWH-01 with different doses (10 g/kg, 5 g/kg, 2.5 g/kg, 1.25 g/kg, 0.625 g/kg), we examined numbers of deaths, general signs, weight measurement and histopathological examination for both sexes of rats. Summaried results are: 1) No deaths were occurred, 2) There were no pathological and clinical differences compared with control group, 3) No significant changes of body weights were observed, and 4) In histopathological examinations of organs and tissues, there was some hemorrhage in a lung tissue of low dose group for male and female respectively, but it was thought to be caused by environmental factor. The results suggest that toxicity of DWH-01 is low and its $LD_{50}$ is over 10 g/kg in Sprague-Dawley rats.

HRccine was administered subcutaneously for 4 weeks to rabbits at dose levels of 300, 60 and 12 times the expected clinical dose to evaluate the subacute toxicity. There were no effects in clinical signs, body weight changes, food consumption, water consumption, urinalysis and blood biochemistry in any animals tested. In hematological examinations, decrease of lymphocyte counts and increase of platelet counts were observed in the medium- and high-dose treated groups. Absolute weights of thymus were tending to decrease, but no pathological changes were observed in microscopic examinations. The no-effect dose in subacute toxicity study of rabbits was considered to be 300 times the expected clinical dose.
