Maximum dose doxycyclineThese levels were 1 9 + - micrograms ml mean + - standard deviation ; 2 h after drug administration, 1 + - 3 micrograms ml 8 h after drug administration and 2 h after a mean of 4 h cardiopulmonary bypass, and 6 + - 6 micrograms ml 24 h after drug ingestion, for instance, doxycycline hyclat. There has been general acceptance that the antimicrobial activities of tetracycline are common to all of its derivatives 7 ; . The differences in susceptibility apparent in the laboratory are ascribed to the ease with which the various agents gain access to the cell interior. The pharmacological superiority of doxycycline, described by English 5 ; , is sufficient reason for serious study with this analogue of tetracycline. Indeed, the present investigation indicates that, in general, in vitro results with doxycycline are the same as with tetracycline derivatives studied heretofore. Thus, E. coli, Klebsiella-Aerobacter group, P. aeruginosa, Lancefield group A streptococci, and pneumococci behave in a predictable fashion; however, the behavior of staphylococci and enterococci toward doxycycline was unexpected. The latter bacteria reacted toward the high-content medicated discs of the three tetracyclines tested with zones of inhibition which are variously characterized as slightly or minimally susceptible by some investigators and as resistant or susceptible by the criteria of others. Although the differences. 16. Ljungstrom, I., and G. Huldt. 1977. Effect of experimental trichinosis on unreleated humoral and cell mediated immunity. Acta Pathol. Microbiol. Scand. Sect.

Sanctions or enticements in the family, employment setting, or criminal justice system can increase significantly both treatment entry and retention rates and the success of drug treatment interventions. Possible Drug Use During Treatment must be Monitored Continuously. Lapses to drug use can occur during treatment. The objective monitoring of a patient's drug and alcohol use during treatment, such as through urinalysis or other tests, can help the patient withstand urges to use drugs. Such monitoring also can provide early evidence of drug use so that the individual's treatment plan can be adjusted. Feedback to patients who test positive for illicit drug use is an important element of monitoring. Treatment Programs Should Provide Assessment for HIV AIDS, Hepatitis B and C, Tuberculosis and Other Infectious Diseases, and counseling to help patients modify or change behaviors that place themselves or others at risk of infection. Counseling can help patients avoid high-risk behavior. Counseling also can help people who are already infected manage their illness. Recovery From Drug Addiction can be a Long-Term Process and Frequently Requires Multiple Episodes of Treatment. As with other chronic illnesses, relapses to drug use can occur during or after successful treatment episodes. Addicted individuals may require prolonged treatment and multiple episodes to achieve long-term abstinence and fully restored functioning. Participation in self-help support programs during and following treatment often is helpful in maintaining abstinence.

MEASUREMENT OF 17-HYDROXYPROGERSTONE 17OHP ; IN TUMOR-BEARING DOGS AND DOGS WITH SUSPECTED HYPERADRENOCORTICISM. EN Behrend, AL Boozer, EM Whitley, KA Busch, RJ Kemppainen. Auburn University College of Veterinary Medicine, Auburn, AL. Recently, measurement of 17OHP has been advocated as a means for diagnosis of occult canine hyperadrenocorticism. However, the sensitivity and specificity of this test has not been defined. Our objectives were to assess serum 17OHP concentration pre- and postinjection of ACTH in tumor-bearing dogs and in dogs being screened for hyperadrenocorticism HAC ; . In Phase I, ACTH stimulation tests were performed on 16 normal and 33 tumor-bearing dogs. Plasma endogenous ACTH eACTH ; was measured in the baseline plasma sample of the tumor-bearing dogs. Trasylol was added to all blood samples used for measurement of eACTH. For the ACTH stimulation test, Cortrosyn was injected 5 mcg kg IV ; and blood samples taken before and 1-hr after injection. For statistical comparison of serum 17OHP concentrations between normal and tumor-bearing dogs, the Mann-Whitney Rank Sum Test was used. The relationships between serum cortisol, 17OHP and plasma eACTH concentrations were assessed using linear regression analysis. Statistical significance was set at p 0.05. In Phase II, samples from 127 ACTH stimulation tests submitted to the Auburn Endocrine Diagnostic Service for screening for canine HAC were used. The reference range for post-ACTH serum 17OHP concentration was 0.1-2.8 ng ml. Serum 17OHP concentration post-ACTH was significantly higher in tumor-bearing dogs than in normal dogs p 0.0130 ; . Ten tumor-bearing dogs had an elevated post-ACTH serum 17OHP concentration yielding a 70% specificity for diagnosis of HAC. Although the pre-ACTH serum cortisol and 17OHP concentrations were significantly correlated R 0.67, p 0.001 ; , neither concentration correlated with endogenous ACTH concentration R 0.044 and 0.13, respectively ; Of the 127 dogs suspected to have HAC, 68 had a normal postACTH serum cortisol concentration. Of these 68 dogs, 10 15% ; had an elevated post-ACTH serum 17OHP concentration. Of the 59 dogs with an elevated post-ACTH serum cortisol concentration, 17 29% ; had a normal post-ACTH serum 17OHP concentration the rest had values above normal ; . Our results suggest: 1. Measurement of post-ACTH serum 17OHP concentration has a relatively low specificity for diagnosis of HAC. 2. In tumor-bearing dogs, secretion of neither 17OHP nor cortisol is related to eACTH concentration. 3. In dogs suspected to have HAC, if post-ACTH serum cortisol concentration is normal, post-ACTH serum 17OHP concentration also is normal in the majority of cases. 4. Approximately 30% of dogs suspected to have HAC with an elevated post-ACTH serum cortisol concentration have a normal post-ACTH serum 17OHP concentration. While it is unclear whether the 10 dogs suspected of HAC with normal post-ACTH serum cortisol but high post-ACTH serum 17OHP would have benefited from mitotane therapy, the data suggest that post-ACTH serum 17OHP values may not necessarily correlate with adrenal hyperfunction and indocin. ABSTRACTS OF XXXIII ANNUAL CONFERENCE RATIONAL USE OF DRUGS AND ESSENTIAL DRUGS AT THE UNDERGRADUATE LEVEL MUKUL MATHUR, SAROJ VANJANI Dept. of Pharmacology, S.M.S. Medical College, Jaipur-302 004. Objective: Preliminary studies investigating the use of drugs in children suffering from actute diarrhoea and in patients receiving the treatment from general surgeons and urologists for various ailments have been quite revealing. Methods: ORS alone was prescribed to only 1.3% of children while, in combination with other drugs, namely antibiotics, antimotility, antispasmodics, lactobacillus containing preparations, antiemetics, NSAIDS, it was prescribed to about 66% of the total cases. There was a high incidence of antibitoic prescriptions amongst general surgeons and urologitsts, both for prophylactic and curative purposes. However, the noteworthy feature was that the prescriptions were largely emperical in that urine culture and sensitivity testing was not performed. More than one antibiotic was commonly prescribed for long duration in some cases more than 15 days ; and in some prescriptions the duration of antibiotic use was not mentioned. Results: These results strongly emphasize the need for creating a greater awareness amongst prescribers towards rational use of drugs through CMEs, seminars etc. Introducing the concept of RUD its evolution, importance, necessity and benefits and practice at the undergraduate level is likely to help immensely in curtailing inappropriate use, much to the relief of the patient and the society. Conclusion: It is proposed that concept of rational use of drugs and essential drug list be introduced in the phamacology curriculum at the undergraduate level. 136. UNDERGRADUATE PHARMACOLOGY TEACHING: CURRICULUM REFORM SHAH V.R., REGE N.N., DAHANUKAR S.A. with contribution from Pharmacology teachers of all Medical Colleges of Maharashtra affiliated to MUHS Department of Pharmacology and Therapeutics, Seth GSMC & KEMH, Parel, Mumbai-400 012. Objective: Consolidated efforts by te teachers of Pharmacology from Maharashtra to bring uniformity in the curriculum all over the state using principles of Medical Education Technology are presented in this paper. Methods: The board of studies for paraclinical subjects, MUH convened a workshop in October 1999 inviting representatives from each of the 33 medical colleges in Maharashtra. Prior to this, seveal institutional and regional meetings were held so as to reach a consensus regarding topics in syllabus, teaching learning experiences & examiniation pattern. During the workshop, morning sessions were devoted to various aspects of Medical Education Technology like curriculum planning, process of evaluation, formulation of MCQs, intergrated teaching etc. Taking a cue from the morning sessions, during the afternoons, participants in each discipline deliberated on their own curriculi adapting to the facilities and needs of various institutes located in rural and urban areas. Results: A revised curriculum in pharmacology thus emerged, ready for transaction and accessible on the net. The highlights of this curriculum are shift from knowledge-based learning to skill acquisition analytical, psychomotor and cummunicative ; , emphasis on process of rational selection and prescribing of drugs. Rectal and pharyngeal infections. Norfloxacin eradicated equally well N. gonorrhoeae susceptible or resistant to penicillin and produced results comparable to those with spectinomycin in a nonrandomized comparative study 127 ; . Ciprofloxacin 100 to 500 mg ; 467, 628, 677, ; , ofloxacin 200 to 600 mg ; 15, 89, 622 ; , enoxacin 400 to 600 mg ; 552, 705, 760, ; , and fleroxacin 400 mg ; 57, 438 ; in single doses have also been highly effective in curing uncomplicated gonorrhea. Infections involving the urethra or uterine cervix were almost uniformly cured. Occasional failures were seen, however, in infections of the rectum 628, 760 ; and pharynx 57, 677 ; , but these failures appeared to occur less commonly with norfloxacin than with a combination of ampicillin and probenecid 401 ; . A single case of cure of gonococcal salpingitis with ciprofloxacin given for 7 days has been reported 493 ; . The only report of treatment of disseminated gonococcal infections with quinolones was of two patients with gonococcal arthritis cured with ciprofloxacin 608 ; . There is only a single report of an isolate of N. gonorrhoeae resistant to fluoroquinolones appearing after enoxacin therapy in humans 812 ; , but it has been possible to select resistant isolates in vitro 630, 812 ; . Single doses of norfloxacin 61, 638 ; , ciprofloxacin 628, 677, 690, ; , ofloxacin 15 ; , and enoxacin 552, 760, 802 ; have all failed to prevent the development of postgonococcal urethritis in men, and in some studies a high frequency of persistence of Chlamydia trachomatis has been documented. More prolonged therapy for 7 to 10 days with norfloxacin 75 ; and ciprofloxacin 235 ; has also produced little or limited eradication of Chlamydia trachomatis in patients with nongonococcal urethritis. In the latter study, ciprofloxacin was significantly less effective than doxycycline. Interestingly, despite the observation that Chlamydia trachomatis is more susceptible than U. urealyticum to fluoroquinolones in vitro, a higher fraction of patients with nongonococcal urethritis caused by U. urealyticum was cured by norfloxacin 75 ; and ciprofloxacin 235 ; than those with Chlamydia trachomatis, and ciprofloxacin appeared to be more effective P 0.12 ; than doxycycoine 235 ; . In contrast, ofloxacin 200 mg twice daily ; 50, 243, 530, ; or fleroxacin 400 to 800 mg per day ; 603 ; given for 5 to 15 days eradicated Chlamydia trachomatis from the urethra or cervix in 90% of patients, a result comparable to that with doxycycline in one study 243 ; . Urethritis that was culture negative for chlamydia responded to ofloxacin less well in men 530 ; . Additional comparative studies are needed. Chancroid has responded to treatment with ciprofloxacin 54, 519, 774 ; and enoxacin 495 ; . In the only comparative study, ciprofloxacin 500 mg twice daily ; given for 3 days produced rates of clinical and bacteriologic cure similar to or slightly better than standard therapy with TMP-SMX given for the same period 519 ; . A single dose of ciprofloxacin 500 mg ; also appears to be effective in sterilizing and promoting healing of the genital ulcers of chancroid 54, 774 ; . No data are available in humans on the response of incubating syphilis to fluoroquinolones. In the only studies to date, ofloxacin was not active against T. pallidum in an animal model of infection 595, 790 ; . Thus, patients with other sexually transmitted diseases treated with quinolones alone should be monitored for the development of syphilis and isordil.
