Since the pattern of the frequency distribution of a parasite within a host showed an overdispersed pattern, various statistical models such as Poisson, negative binomial and lognormal distributions have been applied on the population dynamics in host-parasite relations. The observed data on the number of metacercariae of Clonorchis sinensis in a suitable intermediate host, Pseudorasbora parva which were collected from an endemic area, Juk-Rim River, Kim-Hae Goon, South Kyong-Sang Do were applied on the statistical models. The results obtained are as follows: By the calculation of the raw data, 258(94.9 percent) out of 272 fish showed positive to the metacercarial infection of C. sinensis. The mean number of metacercaria in a fish was 335.1. The standard deviation was 250.6 and the mode was observed between 250 and 299. The frequency distribution pattern of metacercariae of C. sinensis within the fish host in surveyed area was fitted to the lognormal distribution (0.05 parasitology-helminth-trematoda ; Clonorchis sinensis ; metacercaria ; Pseudorasbora parva ; frequency distribution ; host

To understand the mode of transmission in clonorchiasis, a survey was made in Kim-hae Goon, South Kyong-sang Do (=Province). The mathematical analysis of the age prevalence was done on the egg positive rates. And another analysis for the comparison was also made to the cited data from two areas, North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do. Some catalytic models of H. Muench (1959) were applied to the observed age prevalence. Because the both parameters, such as force of infection(a) and loss of positivity(b) were considered to be constant for a long period in the surveyed area, the two stage catalytic model by Muench was chosen to the analysis. In the surveyed area, Kim-hae Goon where the egg positive rates were 56.2 percent and 61.2 percent (by Kim, 1974), the constant values of 'a' were found to be 0.051 and 0.089 respectively. In other words, the force of infection was 51, 89 per 1,000 susceptibles. The values of 'b' were found to be 0.006 and 0.005. This means that the rates of disappearance from egg positive cases to negative were 6 and 5 per annum per l,000 positive cases in above area. Therefore, the two catalytic curves were expressed by the following equations, y = 1.133 {e(-0.006t) - e(-0.051t)} and y = 1.047 {e(-0.005t) - e(-0.089t)} respectively. In the cases of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do where the egg positive rates of clonorchis shown as 27.7 percent and 15.2 percent by Shin (1964) and Kim (l974), the curves were expressed by y = 1.769 {e(-0.010t) - e(-0.034t)} and y = 2.857 {e(-0.020t) - e(-0.027t)} respectively. From the above mathematical analyses by age prevalence in clonorchiasis, it was considered that the mode of transmission of clonorchiasis in the surveyed area, Kim-hae Goon presented more rapid pattern than those of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do.

We have investigated the clinical response of 12 patients with erythrodermic psoriasis to therapy with etretinate. Initial dosage of etretinate was 20-60mg/day. The time for complete disappearance of scales averaged 19.9 days. In 10 of 12 patients(83.3%) satisfactory results were obtained after 2 to 11 months of treatment. Cheilitis was the most common side effect. Three patients had mild elevation of blood lipids, which was corrected by dose reduction. Remission period, of ten patients who showed good result, averaged 4.2 months.

Background: The Life-Sustaining Treatment Decision-Making Act has allowed anyone aged 19 or older to sign an Advance Directive not to receive life-sustaining treatment when they are in the ‘death process’. Recently, the Korean Pharmaceutical Association announced to raise awareness of the Advance Directive to the general public through community pharmacies across the country. This study aimed to investigate the public’s willingness to accept pharmacist’s consultation regarding the Advance Directive and to present future directions to pharmacists Methods: This cross-sectional questionnaire study using 16-items was conducted in adults, Study subjects were recruited by convenience sampling method during August 5-15, 2020. Results: Of 460 respondents, 51.7% were younger than 30-year-old and 58.7% were not in the healthcare field in terms of job or major. 60.2% knew about the Advance Directive and 81.7% agreed the necessity to sign when healthy. 50.0% had the willingness to consult with pharmacists on the Advance Directive for well-dying and 80.4% preferred verbal explanation together with written information. Simple linear regression analysis results showed a significant relationship between trust in pharmacists or satisfaction with pharmacist’s communication and willingness to use pharmacist’ consultation on the Advance Directive (1-point increases in values measured on a five-point scale are associated with 0.464 and 0.486 increases, respectively.) Conclusion This study suggests that pharmacists need to improve the public’s trust and communication capability to satisfy with public’s demands on well-dying service.

Early diagnosis of persistent abnormal reflexes may be of great significance to a more effective functioning of the cerebral palsied child. It is important to know the normal and abnormal reflex responses and their effect upon motor development for providing a basis for evaluation in the diagnosis and treatment of the cerebral palsied child. We studied 28 cerebral palsied children, between 1 to 12 years old, who were treated at Sam Yook Childrens Rehabilitation Center from May 1975 to December 1977. The pathologic reflexes were checked, and the relationship between pathologic reflexes and walking was compared. The following results were obtained. 1. The following were the most important pathologic reflexes in non-walking fgroup: a. Positive supporting reaction b. Protective extensor thrust c. Moro reflex 2. If they are present, the prognosis for walking ambulation was bad and surgery will not improve for the chances of walking.

The os subfibulare is a relatively uncommon bony anomaly of the foot. It is usually found between the malleolus and talus and ossifies during adolescence or preadolescence. It can be demonstrated on routine anteroposterior ankle film of the foot. In 4 patients presented, the abnormality caused pain and frequent episodes of ankle strain. The pain was relieved in all patients treated by excision of the accessory bone.
