  • This is a case report that dysautonomia and catatonia are accompanied by Akinetic Mutism in a 28 year old patient whose symptoms, seemed to catatonic schizophrenia. This study is aimed to assist about comprehension, diagnosis and treatment of dysautonomia and catatonia are accompanied by Akinetic Mutism, because this case is not common. This patient's chief complains that hyperhidrosis, muscular rigidity, akinesia etc are seemed to Neuroleptic Malignant Syndrome. Neuroleptic Malignant Syndrome is a side effect during taking antipsychotic that unknowned high, fever, stupor, muscular rigidity, akinesia, tachycardia, hyperhidrosis, salivation. We cannot rule out Neuroleptic Milignant Syndrome, but this case is seemed to catatonic schizophrenia. The symptoms of catatonic schizophrenia is that prodrome(relaxed concern, ataraxy, lacked concentration) is progressed and akinesia, mutism, ankylosis, stupor etc, are appeared. Oriental medicine, environment with more objective study and treatment are needed.

  • The acute oral LD5O toxicity values of isazofos, pyraclofos, diazinon and methomyl were determined for Japanese quail based on OECD guideline. The $LD_{50}$ of isazofos, pyraclofos and diazinon was 16.26 mg/kg, and 7.11mg/kg body weight In female respectively. And the $LD_{50}$ of each chemical in male was 21.44, 35.64, 8.28 mg/kg body weight respectively. Diazinon was the most susceptible compounds to Japanese quail in both sexes. The $LD_{50}$ of methomyl was 21.24 mg/kg body weights in female, and 28.28 mg/kg body weight in male respectively. Diazinon, isazofos and methomyl were more toxic In the female than male. The symptoms of poisoning were similar in quails administrated with each chemicals. The clinical sign in Japanese quail were ataxia, salivation, diarrhea, ruffled feather and convulsion at dead point. There were severe hemorrhage and catarrhal inflammation from duodenum to ileum In all compounds. In Japanese quail treated with organophosphorus and carbamate compounds, brain acetylcholinesterase was inhibited by 88-96. The recovery was not observed after 5 h in sublethal dose.

  • Single subcutaneous administration to S.D rats of both sexes was performed to investigate the acute toxicity of Syndella gel, a new topical drug containing deproteinised dialysate of calf's blood and micronomicin sulfate. $LD_{50}$ values for S. D rats were 23,047 mg/kg for male and 23,725 mg/kg for female. The death occurred within 24 hours after administration at doses over 19,200 mg/kg. The main cause of death seemed to be respiratory disturbance by acute shock. Major general symptoms induced by injection subcutaneously with Syndella gel were underactivity, decreased respiratory rate, salivation, tremor and loss of consciousness. No significant body weight changes and gross findings of internal organs in treatment groups in comparison with those of control groups was observed at any dose levels in Syndella gel.

  • Pathological studies on 6 milk goats administrated with urea were carried out to determine the effects of acute and chronic poisonings on the animal. Clinical signs appeared about 10 minutes after ingestion of the urea and they consisted chiefly in dullness, staggering, uncontrolled urination, dyspnea, frothy salivation, bloating, muscular tremor, humping of back and tetanic spasms. Macroscopic lesions were failure of blood clot, frothy and bloody contents in the highly congested respiratory tract, pulmonary edema, rumenitis and abomatitis accompanying with petechiation of the upper small intestine. Microscopically, the liver showed vacuolar degeneration, fatty change and areas of necrosis and partial proliferation of the interlobular connective tissues in chronic crises. The renal epithelium displaced vacuolar degeneration, necrosis and hyaline casts in their lumens. In the lungs, there were hyperemia, edema, hemorrhages, and acute catarrhal bronchitis. Neuronal degeneration and necrosis in the central nervous system, catarrhal rumenitis, abomatitis, doudenitis and myocardial hemorrhage were also demonstrated.

  • To study the effects of oxytocin and three parasympathomimetic drugs such as neostigmine, bethanechol, and pilocarpine in reduction of interval between birth and incidence of intrapartum stillborn pigs, 213, sows and gilts which had been kept under the same condition, were randomly allotted to 4 treatment and one control groups. The side reactions of three parasympathomimetic drug were also examined. The results obtained were summarized as followings. 1. Parasympathomimetic-treated groups revealed tendence to shorter interval between birth than oxytocin-treated or control groups. 2. Stillbirth rate per litter was significantly less (p<0.01) in the parasympathomimetic-treated groups than in the oxytocin-treated or control groups. 3. Moderate to severe salivation and vomiting were found in many clams of the pilocarpine-treated and bethanecol-treated groups. The neostigmine-treated group showed nearly no side reaction and neostigmine found to the safest among three parasympathomimetic drugs.

  • Oral appliances therapy is becoming increasingly recognized as a successful treatment for snoring and obstructive sleep apnea(OSA). Compared with continuous positive airway pressure(CPAP), the gold standard therapy for OSA, oral appliance therapy are less efficacious for severe OSA but are more acceptable and tolerable for patients, which in turn, may lead to a comparable level of therapeutic effectiveness. Nevertheless, the various side effects of oral appliance therapy, such as, increased salivation or dryness, pain or discomfort in the teeth or gums, occlusal discomfort in the morning, temporomandibular disorders, dental and occlusal changes may cause discontinuation of treatment or changes in treatment plan. Therefore, oral appliance therapy should be provided by a qualified dentist who can evaluate oral tissues, occlusion, and temporomandibular joints, and prevent and manage the possible side effects.

  • A 2-month-old, 50 kg male Korean native calf was referred with bilateral mandibular fractures. The bilateral mandible was hanging loose, with inability to use the jaw, indicated by excessive salivation. Radiography revealed a long oblique fracture in the right mandible, and a short oblique fracture in the left mandible. Computerized Tomography, a different form of radiography, revealed the fracture in the left mandible to be a comminuted fracture. In order to stabilize the bilateral mandible fractures, a combination of bone plate and wiring was applied; in addition, resin was applied to enhance stabilization of the mandible. Six weeks after surgery, the calf was able to masticate and ruminate well. In this case, application of the plate and wiring with resin to bilateral mandibular fractures presented a successful functional recovery. Accordingly, the combination of bone plate and wiring with resin can be an effective technique for treating mandibular fractures.

  • To assess the testicular toxicity induced by DA-125, a new anthracycline anticancer agent, the test substance was intraveneously administered to male beagle dogs at dose levels of 0, 0.0023, 0.0375, 0.15, and 0.6 mg/kg/day, 6 days a week for 26 weeks. At 0.6 mg/kg/day, 1 out of 3 dogs had died on day 42 of treatment and the other dogs were sacrificed on days 46 and 122 of treatment due to the increasingly severe clinical condition. Clinical signs considered to be related to treatment were included anorexia, vomiting, salivation, decreased activity, mucous and/or dark faeces, diarrhea, and swelling, abscess and/or ulceration of injection sites. Suppression in body weight gain, reduction in food intake, decreases in testicular weight and size, and hemorrhage of epididymis were also observed in male dogs. Microscopically, severe degenerative changes such as atrophy of seminiferous tubules, loss of germ cells, degeneration of germ cells, vacuolization of Sertoli cells, and hyperplasia of Leydig cells were observed in all dogs. Azoospermia in epididymal tubules, atrophy of epithelia in the cauda epididymis, and prostate atrophy were also found. At 0.15 mg/kg/day, anorexia, vomiting, salivation, diarrhea, and swelling of injection sites were observed. In addition, suppression in body weight gain and decreases in testicular weight and size were found in male dogs. Atrophy of seminiferous tubules, decrease of germ cells, degeneration, exfoliation and retention of germ cells, vacuolization of Sertoli cells, and hyperplasia of Leydig cells were observed by histopathological examination. Azoospermia in epididymal tubules and prostate atrophy were also found. At 0.0375 mg/kg/day, there were no clinical signs considered to be indicative of a reaction to treatment, but testicular size was significantly reduced. Microscopically, decreases in the number of spermatogonia and epidydimal speramtozoa were found. There were no evidences of general or testicular toxicity at 0.0023 mg/kg/day. These results indicate that DA-125 produces significant and persistent damage to the spermatogenic compartments of the testes in male beagle dogs.

  • Objectives : The object of this study was to obtain acute toxicity information (single oral dose toxicity) of Armeniacae Semen (AS), a medicinal herb used for treating constipation and various respiratory diseases, in rats. Methods : In order to observe the $LD_{50}$ (50% lethal dose), approximate lethal dosage (ALD) and target organs, AS aqueous extracts were orally administered once to female and male Sprague Dawley rats at dose levels of 2,000, 1,000, 500 and 0 (control) mg/kg (body weight). The mortality, changes in the body weight, clinical signs and gross observation were monitored for 14 days after single oral treatment of AS extracts, and the organ weights and histopathological findings of principle organs were observed after sacrifice. Results : After single oral treatment of AS 2,000 and 1,000 mg/kg, all (5/5; 100%) female and male rats died within 30 minutes after treatment, while no mortalities were observed in the female and male rats treated with 500 mg/kg of AS extract. Therefore, $LD_{50}$ in female and male rats was calculated as 741.95 mg/kg. Seizure, loss of locomotion, salivation, increases of respiration and heart-beat were observed after AS extract treatment, which were observed in all rats including the lowest dosage group, 500 mg/kg in the present study. In addition, lung congestion was visible in all mortal rats with AS 2,000 and 1,000 mg/kg, respectively. Conclusions : The results obtained in this study suggest that AS extract ranges in Class III, because the $LD_{50}$ and ALD in both female and male rats were calculated as 741.95 mg/kg and 500~1,000 mg/kg, respectively. However, AS extract should be carefully treated at clinical applications, because salivation, increase of respiration and heart-beat were also observed in the lowest dosage group, 500 mg/kg in the present study.

  • The objective of this study is to characterize a toxicity of Polygalae Radix (PR) in F344 rats and to find a dose levels for the 13 weeks toxicity study. PR is well known as medicinal herb in many Asian countries for treatment of expectorant, tonic, tranquillizer, antipsychotic agent and functional diet for improving memory. However, there is insufficient background information on toxicological evaluation of PR extract to support its safe use. Therefore, we conducted toxicological evaluation of this drug in compliance with OECD and KFDA guideline in this study. The extract of PR was administered orally to F344 rats at dose levels of 0, 500, 1000, 2000, 3500 and 5000 mg/kg/day for 2 weeks. Each group was composed to five male and five female rats. In the result, there were no treatment PR-related adverse changes in food consumption, hematology, clinical chemistry, urinalysis, gross finding at necropsy, organ weight examination. Four males at 5000 mg/kg/day were found dead during the treatment period. These animals showed salivation. The cause of death is still under investigation. The animals treated at 500, 1000, 2000, 3500 and 5000 mg/kg/day showed salivation and all animals at 5000 mg/kg/day exhibited lower body weight and cumulative weight gain in compared to those of control animals. Therefore, we recommend that a dose group of 3500 mg/kg/day is a highest treatment group in 13-week exposure study.
