Objectives : The purpose of this study was to assess anti-depressive effects of Bee Venom(BV) on an Animal Model of Depression induced immobility stress. Methods : There was 2 pre-experiments MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and Western blot test and 3 main experiments ; forced swimming test, tail suspension test and Y-maze task. Male rats were used for main experiment. The subject was divided into 4 groups(1. control group injected only saline, without immobility stress 2. Negative group injected saline after 2 hours immobility stress 3. Positive group injected Amitriptyline after 2 hours immobility stress 4. BV group injected Bee Venom after 2 hours immobility stress). Each group consisted of 6 rats. Forced swimming test, tail suspension test, Y-maze task were used to evaluate anti-depressive effect of Bee Venom. Results : In MTT assay, as the density of BV increased, the existence rate of primary neuronal cell increased. In Western blot test, the density of CREB and AKT was increasing as time went by. In forced swimming test, BV group showed immobility decreased more than Normal group and Positive group. In tail suspension test, Normal group and Positive group showed immobility decreased more than BV group. In Y-maze task, BV group showed immobility decreased more than Normal group, but Positive group showed immobility decreased more than BV group. Conclusions : These results suggest that Bee Venom may have anti-depressive effect on depression.

Endoscopic diagnosis and medical management from K43 and C45 patients, whose sex, occupation, character and life patterns are quite different each other, were discussed. The K43 was patient with erosive gastritis, which may caused by maldietary habits and life stresses. Although the effective drugs such as H2-receptor antagonists with atacids, H+/K+-pump inhibitors, prokinetics, colloidal bismuth, and sucralfates, were administrated for long time, symptomatic relief of abdominal pain was not improved. The tests of clinical phathology and abdominal sonogram were normal, visceral hypersensitivity was appeared from barostat test of stomach. However C45 had taken headache during every day life, and endoscopically confirmed as a gastric·duodenal ulcer patiant, which may caused by chronic use of NSAIDs. The her ulceric symptoms were suppressed from active stage to healing stage by using combination therapy for H. pylori with traditional antipeptic ulcer drugs, where as amitriptyline was administrated to the K43 but not effective. Nonulcer dyspepsia and irritable bowel syndrome is pooly defined, and affect about 15% of the population annually in U. S. A. but don't seek medical care. Author would like to point out that statistics for visceral pains are absent in Korea.

Purpose: To determine the extent and rate of prescription drug therapy, especially polypharmacy and the prevalence of potentially inappropriate medication use in Korean elderly ambulatory patients based on an explicit criterion. Methods: Performed a retrospective study of 65 years or older ambulatory patients visiting a university hospital based clinic from January 2002 to April 2004. Study determined the patterns of drug prescription per Anatomical Therapeutic Chemical Classification and the potentially inappropriate medication usage based on explicit Beers criteria. Results: Of the 4,042 elderly patients the mean number of prescription was $2.2{\pm}2.0$, which was similar between genders and all age groups within the elderly. 10.7% of patients were prescribed with more than 5 medications concurrently. The most frequently prescribed medication was the drugs used for treating nervous system diseases (44.3%), followed by alimentary tract/metabolism disorders (27.6%), cardiovascular disease (10.7%), blood/blood forming disorders (4.3%), respiratory disorders (6.5%), and musculoskeletal diseases (3.2%). A total of 511 elderly (13%) was prescribed with medication that met the criteria for=1 potentially inappropriate drugs for the elderly. This proportion was similar between genders and all age groups within the elderly. Among these 511 elderly patients the mean number of potentially inappropriate drugs prescribed was $5.1{\pm}3.3$ drugs. Potentially inappropriately prescribed drugs included amitriptyline (76 cases), diazepam (69 cases), ketorolac (57 cases), short acting nifedipine (44 cases), triazolam (38 cases), and hydroxyzine (38 cases). Conclusion: Potentially inappropriate drug prescribing in Korean ambulatory elderly patients are common. Education programs and interventions aimed at optimizing the prescribing and dispensing of the most appropriate drugs are needed.

Postherpetic neuralgia is frequently painful, incapacitating, mood depressing, and sometimes lifelong. We investigated the influence of duration from eruption to nerve blocks in conjunction with patients age on analgesic and preventive effect for postherpetic neuralgia. We retrospectively evaluated 50 outpatient medical records for the above T4 dermatome. Patients had been referred to pain clinic and were treated over 2weeks from Jan. 1988 to Dec. 1993. Fifty patients were divided into 4 groups as follows: Group I (a): less than 4weeks from eruption to nerve block and younger than 65 years old. Group I (b): less than 4weeks from eruption to nerve block and older than 65 years old. Group II (a): more than 4weeks from eruption to nerve block and younger than 65 years old. Group II(b): more than 4weeks from eruption to nerve block and older than 65 years old. Mean number of stellate ganglion blocks were 29.7. Tramadol, amitriptyline, nicardipine were most commonly prescribed. Group I (a): had the most improvement rate(77.8%) as compared with other group(46.6, 52.7, 56.0%). Number of patients who complained of severe pain (VAS > 5) were 0, 3(39%), 2(15.4%), 5(30%) in I (a), I (b), II (a), II (b) group respectively. In conclusion, analgesic effect was best in cases of patients younger than 65 years old whose treatment were started within 4 weeks of eruption. Patients older than 65 yrs, analgesic effect did not vary on the timing of treatment.

TWIK-related $K^+$ channel-2 (TREK-2) and TWIK-related spinal cord $K^+$ (TRESK) channel are members of two-pore domain $K^+$ channel family. They are well expressed and help to set the resting membrane potential in sensory neurons. Modulation of TREK-2 and TRESK channels are involved in the pathogenesis of pain, and specific activators of TREK-2 and TRESK may be beneficial for the treatment of pain symptoms. However, the effect of commonly used analgesics on TREK-2 and TRESK channels are not known. Here, we investigated the effect of analgesics on TREK-2 and TRESK channels. The effects of analgesics were examined in HEK cells transfected with TREK-2 or TRESK. Amitriptyline, citalopram, escitalopram, and fluoxetine significantly inhibited TREK-2 and TRESK currents in HEK cells (p<0.05, n=10). Acetaminophen, ibuprofen, nabumetone, and bupropion inhibited TRESK, but had no effect on TREK-2. These results show that all analgesics tested in this study inhibit TRESK activity. Further study is needed to identify the mechanisms by which the analgesics modulate TREK-2 and TRESK differently.

Anticholinergic drugs are included in the efficacy group of various antidepressants, antihistamines, antispasmodics like skeletal muscle relaxants. Elderly patients are often taking anticholinergic drugs due to various diseases such as sleep disorders and dysuria. But the use of anticholinergic drugs is restricted in guidelines such as Beers Criteria or STOPP due to the anticholinergic adverse effects including dry mouth, constipation, difficult urination, delirium, hallucinations and especially cognitive impairment. In this study, we investigated the usage of anticholinergic drugs in out-of-hospital prescription of 4,442 elderly patients. Results of the study were obtained that 32% (n=1,421) of overall patients were prescribed with 1~6 products (average 1.37) of anticholinergic drugs. 70.9% of the 1,421 patients (n=1,007) were prescribed with one drug, 22.7% (n=323) were two drugs and 4.9% (n=70) were three drugs. 27.1% of the 1,421 patients (n=430) were 70~74 years old patients who were the most commonly prescribed with anticholinergic drugs. Amitriptyline, chlorpheniramine, dimenhydrinate and quetiapine were most frequent component of ACB Score 3 drugs and amantadine, baclofen, carbamazepine, cyproheptadine and oxcarbazepine were most frequent of ACB Score 2 drugs. Anticholinergic Drug Scale (ADS) of individual patients presented one point (48.5%, n=689), 2 points (15.4%, n=219), more than 3 points (36.1%, n=513), and up to maximum 12 point (n=1). More than 2 points were more than half (51.5%, n=732). Therefore, additional prospective study in the use and adverse effects of anticholinergic drugs for elderly patients will be required. And national management such as DUR program will be required for elderly drug administration from now on.

Urinary incontinence (UI), affecting 3%-11% of males and 25%-45% of females globally, is expected to rise with an aging population. It significantly impacts mental health, causing depression, stress, and reduced quality of life. UI can exacerbate psychiatric conditions, affecting treatment compliance and effectiveness. It is categorized into transient and chronic types. Transient UI, often reversible, is caused by factors summarized in the acronym DIAPPERS: Delirium, Infection, Atrophic urethritis/vaginitis, Psychological disorders, Pharmaceuticals, Excess urine output, Restricted mobility, Stool impaction. Chronic UI includes stress, urge, mixed, overflow, functional, and persistent incontinence. Drug-induced UI, a transient form, is frequently seen in psychiatric treatment. Antipsychotics, antidepressants, and other psychiatric medications can cause UI through various mechanisms like affecting bladder muscle tone, altering nerve reflexes, and inducing other conditions like diabetes or epilepsy. Specific drugs like lithium and valproic acid have also been linked to UI, though mechanisms are not always clear. Managing UI in psychiatric patients requires careful monitoring of urinary symptoms and judicious medication management. If a drug is identified as the cause, options include discontinuing, reducing, or adjusting the dosage. In cases where medication continuation is necessary, additional treatments like desmopressin, oxybutynin, trihexyphenidyl, or amitriptyline may be considered.

Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP patients who were treated with eletroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain form stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from $7.7{\pm}1.7$ to $4.4{\pm}2.0$ with pain treatment(p<0.05). In accordance with improvement of ain scores, RS and MBI scores ere also improved from $2.88{\pm}0.95$ to $2.13{\pm}1.01$ and from $83.0{\pm}16.9$ to $94.7{\pm}9.5$(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

항우울약인 rolipran(RP)등 phosphodiesterase-억제 약(PDE-1)들이 thrombin(TB: 0.25 U/ml)에 의한 혈소판 응집에 미치는 작용을 가토-혈소판에서 일차 검토하였다. 신 PDE-1인 KR-30075(KR)의 $IC_{50}$/은 sodim nitroprusside의 것보다 낮았고 PDE-1들은 혈소판내 cAMP와 cGMP를 증가시켰으며 특히 KR은 타 PDE-1와 달리 I $P_3$를 감소시켰다. 아울러 rolipram은 cGMP와 I $P_3$를 증가시켰으나, amitriptyline(AT), sertraline(57), chlorpromazine(CP) 및 spermine은 I $P_3$를 증가시켰다. 그러나 이들과 PDE-1들은 강도의 차이는 있으나 모두 TB에 의한 혈소판응집을 모두 억제하였다. 따라서, PDE-1 중 IBMX(2$\times$$10^{-5}$M), KR(5$\times$10$_－7/M), 및 rolipram(10$_{-3}$M) 그 외에 항우울약인 AT(1.5 $\times$10$_－4/M) 와 ST(10$_－4/M) 및 항정신병약인 CP(10$_－4/M)둥이 혈소판내 I $P_3$, [C $a^{＋＋}$], Tx $B_2$, 및 PG $I_2$ 함량과 단백-인산화의 TB에 의한 변동에 미치는 영향을 검토하였다. 그 결과 TB에 의한 혈소판내 I $P_3$, [C $a^{＋＋}$], Tx $B_2$, 및 PG $I_2$ 함량의 증가가 PDE-1들과 항우울약들에 의하여 억제되었다 단, 항우울성약들과 CP는 정상 혈소판 I $P_3$를 증가시켰다. 아울러 혈소판-단백인산학에서 TB는 41-43 kD와 20 kD의 인산화를 현저히 증가시키며 19 kD의 인산화는 감소시켰고, PKC의 기질인 41-43 kD와 20 kD의 단백인산화가 PDE-1들과 항우울약들 뿐 아니라 CP에 의하여 현저히 억제되었다. 단, 20 kD 인산화에 대한 AT의 억제작용은 미약하였고, cAMP와 PDE-1들은 22kD 인산화를 증가시켰다. AT, ST, 및 CP는 A23187에 의한 41-43 kD 인산화는 현저히 억제하나 20 kD 인산화에는 영향을 미치지 않았고, PMA(3.2$\times$$10^{－7}$ M)에 의한 단백인산화에 대하여는 더 미약한 억제-효과를 나타내었다. 이상의 결과는 PDE-1과 항우울약들의 항혈소판작용은 PKC-기질인 41-43 kD와 20 kD의 인산화를 억제함에 기인되는 것으로 사료된다.다. 것으로 사료된다.다.

Many evidences are compatible with the correlation between the inhibition of [$^3H$] imipramine([$^3H$]IMI) and [$^3H$]paroxetine([$^3H$]PAT) binding to the 5-hydroxytryptamine(5-HT) transporter complex and the 5-HT uptake of 5-HT neurons and platelets, and most antidepressants have been shown to inhibit the [$^3H$]IMI and [$^3H$]PAT binding and the neuronal 5-HT uptake. However, several paradoxical research findings led to doubt about the pharmacological significance of the [$^3H$]IMI and [$^3H$]PAT binding sites. This study was carried to clarify the correlation between the [$^3H$]IMI and [$^3H$]PAT binding parameters and the tissue 5-HT content or/and [$^3H$]5-HT uptake in the rabbit platelet, which contains 40 times ad much 5-HT as that of human platelet and shows the 10 fold higher $B_{max}$ of the 5-HT transporter binding to a 5-HT uptake inhibitor. The rabbits were treated for 28 days with amitriptyline(4mg/kg/day : AP), fluoxetine(0.5mg/kg/day : FO), and sertraline(0.5mg/kg/day : SA) via an Alzet osmotic pump implanted for constant infusion. The [$^3H$]IMI binding $B_{max}$ and $K_d$ of the rabbit platelets were $6.4{\pm}1.2$pmol/mg protein and $10.9{\pm}2.1$nM and those in the [$^3H$]PAT binding were $8.6{\pm}1.1$pmol/mg protein and $1.6{\pm}0.3$nM, respectively. AP slightly increased $B_{max}$ of [$^3H$]IMI binding and both [$^3H$]IMI binding and [$^3H$]PAT binding $K_d$, and i contrast, it slightly decreased $B_{max}$ of [$^3H$]PAT binding. FO Slightly increased $K_d$ of both and [$^3H$]IMI and [$^3H$]PAT binding and slightly decreased $B_{max}$ of [$^3H$]IMI and [$^3H$]PAT binding. SA produced the significant increase of [$^3H$]PAT binding $B_{max}$ and the slight increase of both [$^3H$]IMI and [$^3H$]PAT binding $K_d$ and in contrast, it slightly decreased $B_{max}$ and of [$^3H$]IMI binding. And, the $V_{max}$ and $K_m$ of platelet [$^3H$]5-HT uptake were $24.2{\pm}2.4$pmol/$10^8$ platelets/min and $3.3{\pm}0.3$nM, respectively. The $V_{max}$ was little affected by AP, FO, or SA, but the [$^3H$]5-HT uptake $K_m$ value was moderately increased by FO. However, the platelet 5-HT content was moderately decreased by all of the 5-HT uptake inhibitors used in this study. These results seem to be consistent with the allosterical and competitive interaction of 5-HT uptake inhibiting antidepressants with each other as well as 5-HT in the 5-HT transporter binding, and provide no support for the view that the potencies of 5-HT uptake inhibitors to inhibit the [$^3H$]IMI or [$^3H$]PAT binding with 5-HT transporter complex correlate with their antidepressant potencies.
