Abstract
The Pooled Uranium Miners Analysis (PUMA) study is the largest uranium miners cohort with 119,709 miners, 4.3 million person-years at risk and 7754 lung cancer deaths. Excess relative rate (ERR) estimates for lung cancer mortality per unit of cumulative exposure to radon progeny in working level months (WLM) based on the PUMA study have been reported. The ERR/WLM was modified by attained age, time since exposure or age at exposure, and exposure rate. This pattern was found for the full PUMA cohort and the 1960 + sub-cohort, i.e., miners hired in 1960 or later with chronic low radon exposures and exposure rates. The aim of the present paper is to calculate the lifetime excess absolute risk (LEAR) of lung cancer mortality per WLM using the PUMA risk models, as well as risk models derived in previously published smaller uranium miner studies, some of which are included in PUMA. The same methods were applied for all risk models, i.e., relative risk projection up to <95 years of age, an exposure scenario of 2 WLM per year from age 18-64 years, and baseline mortality rates representing a mixed Euro-American-Asian population. Depending upon the choice of model, the estimated LEAR per WLM are 5.38 × 10-4 or 5.57 × 10-4 in the full PUMA cohort and 7.50 × 10-4 or 7.66 × 10-4 in the PUMA 1960 + sub-cohort, respectively. The LEAR per WLM estimates derived from risk models reported for previously published uranium miners studies range from 2.5 × 10-4 to 9.2 × 10-4. PUMA strengthens knowledge on the radon-related lung cancer LEAR, a useful way to translate models for policy purposes.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
BACKGROUND The Pooled Uranium Miners Analysis (PUMA) study draws together information from cohorts of uranium miners from Canada, the Czech Republic, France, Germany and the USA. METHODS Vital status and cause of death were ascertained and compared with expectations based upon national mortality rates by computing standardized mortality ratios (SMRs) overall and by categories of time since first hire, calendar period of first employment and duration of employment as a miner. RESULTS There were 51 787 deaths observed among 118 329 male miners [SMR = 1.05; 95% confidence interval (CI): 1.04, 1.06]. The SMR was elevated for all cancers (n = 16 633, SMR = 1.23; 95% CI: 1.21, 1.25), due primarily to excess mortality from cancers of the lung (n = 7756, SMR = 1.90; 95% CI: 1.86, 1.94), liver and gallbladder (n = 549, SMR = 1.15; 95% CI: 1.06, 1.25), larynx (n = 229, SMR = 1.10; 95% CI: 0.97, 1.26), stomach (n = 1058, SMR = 1.08; 95% CI: 1.02, 1.15) and pleura (n = 39, SMR = 1.06; 95% CI: 0.75, 1.44). Lung-cancer SMRs increased with duration of employment, decreased with calendar period and persisted with time since first hire. Among non-malignant causes, the SMR was elevated for external causes (n = 3362, SMR = 1.41; 95% CI: 1.36, 1.46) and respiratory diseases (n = 4508, SMR = 1.32; 95% CI: 1.28, 1.36), most notably silicosis (n = 814, SMR = 13.56; 95% CI: 12.64, 14.52), but not chronic obstructive pulmonary disease (n = 1729, SMR = 0.98; 95% CI: 0.93, 1.02). CONCLUSIONS Whereas there are important obstacles to the ability to detect adverse effects of occupational exposures via SMR analyses, PUMA provides evidence of excess mortality among uranium miners due to a range of categories of cause of death. The persistent elevation of SMRs with time since first hire as a uranium miner underscores the importance of long-term follow-up of these workers.

Abstract
Abstract
Introduction: In New Mexico, Hispanic women have a 1.7-fold increased risk of breast cancer-specific death compared to non-Hispanic white women. In previous studies, race/ethnic minority women have had larger survival disparities in estrogen receptor positive (ER+) than ER- disease, suggesting some aspect of ER may mediate survival outcomes. We thus conducted an extensive assessment of ER quantitative measures.
Objective: To determine whether ER percent positive and intensity differs by ethnicity, and to evaluate whether that potential difference might account for a proportion of survival disparities.
Methods: We conducted a population-based case-cohort study of first invasive breast cancer diagnosed in white females from 1997-2009 in six NM counties, identified through Surveillance Epidemiology End Results (SEER). We selected 15% of breast cancer cases and all breast cancer deaths through 2012. After IRB approval, pathology reports and tissue microarrays served as sources of ER, PR, and Her2 information. Tumors were classified according to modified intrinsic subtypes based on immunohistochemistry. Data were analyzed using Cox proportional hazards models adapted for case-cohort with weighted estimates (cohort weighted by 6.67x), and estimated hazard ratios (HR) and 95% confidence intervals (CI) using the robust variance and alpha=.05. The proportional hazards assumption was verified by Schoenfeld residuals. All analyses were adjusted for age. Interaction was assessed by inclusion of main effects and a product term (subtype* exposure).
Results: ER and intrinsic subtype information was available for 76% of the cohort (867/1143) and 70% of breast cancer deaths (689/991). Median follow up was 7.8 years. In analyses stratified by intrinsic subtype, Hispanic women experienced elevated mortality relative to non-Hispanic whites for luminal A (HR 1.9;95% CI 1.4-2.6), Luminal B (HR 2.9;95% CI 1.5-5.7), and TN tumors (HR 1.9;95% CI 1.0-3.6) but not Her2+ER- disease (HR 1.1;95% 0.3-3.4).
Overall ER Quantitative measures: Among ER+ women, breast cancer mortality decreased with increasing ER+ staining, measured by percent (p-trend=.004) or quartile (p-trend=.002). After adjustment for ER percent(ER%+), women with increased ER intensity (score>2) had reduced mortality, relative to score=1 (HR 0.6;95% CI 0.4-.1.0). Results did not differ by Luminal A or B subtype (p interaction> .05).
Ethnicity-specific ER quantitative measures: ER%+ distribution did not differ by Hispanic ethnicity. However, among Hispanic women, interaction terms for ER%+ (p=.04) or quartile (p=.08) by subtype in relation to breast cancer survival suggest that Hispanic women with increasing ER staining have a reduced risk of mortality in Luminal A but not Luminal B tumors. Such differences were not evident among non-Hispanic white women. In multivariate models, inclusion of ER%+ and staining intensity did not alter Hispanic survival disparity overall, but mediated 8.6% in Luminal B.
Conclusion: After inclusion of ER%+, ER staining intensity is an independent risk factor for breast cancer survival. Differences in ER quantitative measures appear to account for only a small proportion of survival disparities. Survival gaps in ER+ breast cancer may be attributable to host or other tumor factors.Introduction: In New Mexico, Hispanic women have a 1.7-fold increased risk of breast cancer-specific death compared to non-Hispanic white women.

Abstract
This research investigated the reproductive biology (sex ratio, hermaphroditic pattern, size and age at maturity) of Cephalopholis argus, known locally in Hawaii by its Tahitian name roi. The results suggest that C. argus exhibits monandric protogyny (female gonad differentiation with female to male sex change) with females reaching sexual maturity at 1.2 years (95% c.i.: 0.6, 1.6) and 20.0 cm total length (LT ; 95% c.i.: 19.6, 21.2). The female to male sex ratio was 3.9:1. The average age and LT at sex change was 11.5 years (95% c.i.: 11.1, 12.9) and 39.9 cm (95% c.i.: 39.5, 41.2), respectively. Current information on spawning seasonality of this species is incomplete, but based on the occurrence of spawning capable and actively spawning females, spawning probably takes place from May to October. Evidence of lunar spawning periodicity was found, with an increased proportion of spawning capable and actively spawning females, and an increased female gonado-somatic index during first quarter and full-moon phases. This information fills a valuable information gap in Hawaii and across the species' native range.

Abstract
We report on the case of a 34-year old man with a previously refractory high-grade non-Hodgkin's Lymphoma which regressed following dendritic cell based immunotherapy after high-dose chemotherapy. Antigen presenting cells known as dendritic cells were cultured from harvested autologous peripheral blood progenitor cells. The dendritic cells were then exposed to unfractionated tumour peptides derived from a skin biopsy section inflitrated with lymphoma. These charged dendritic cells infused into the patient together with autologous T-lymphocytes after high-dose chemotherapy with peripheral blood stem cell rescue. Although the lymphoma relapsed after the high-dose chemotherapy it regressed again following the dendritic cell infusion. The patient's T-lymphocytes demonstrated in vitro reactivity to tumour peptides whereas the lymphocytes of controls did not. We propose that the lymphoma regression occurred because of a T cell mediated response against the tumour induced by the charged dendritic cells.

Abstract
Abstract
Introduction: In New Mexico (NM), Hispanic women have a 1.6-fold increased risk of breast cancer-specific death compared to non-Hispanic white women. In previous studies, race/ethnic minority women have been less likely to receive recommended adjuvant treatments, including radiation in women undergoing breast conservation, and hormonal therapy.
Objective: To determine whether non-receipt of recommended therapies contributed to disparate survival.
Methods: We conducted a case-cohort study of breast-cancer-specific survival within a population-based cohort of first invasive breast cancer diagnosed in white females from 1997-2009 in six NM counties, identified through Surveillance Epidemiology End Results (SEER). We selected fifteen percent of all women diagnosed with breast cancer and all breast cancer deaths. After IRB approval, data were collected from comprehensive medical chart reviews, supplemented by SEER information. Receipt of standard of care, vs. not, was defined based on age, diagnosis year and tumor characteristics, according to changes in treatment guidelines. Women who had a reported contraindication or refused therapy were omitted from assessment of quality of care for that therapy. Cox proportional hazards models for case-cohort were conducted using weighted estimates, with calculation of robust variance and hazard ratios (HR) and 95% confidence intervals (CI), using an alpha level of .05. Analyses were restricted to women of age 70 or less who survived at least 12 months. The proportional hazards assumption was verified by Schoenfeld residuals. All analyses were adjusted for age.
Results: Comprehensive medical records reviews were completed for 91% of eligible women (674 cohort members, 519 breast cancer deaths; median follow up 7.8 years). All others were omitted from analysis. Of women eligible for guideline-based treatment, receipt of guideline-appropriate therapy did not differ by Hispanic ethnicity for any treatment, and Hispanic women were slightly more likely overall to receive appropriate therapy (difference not significant). Among guideline-eligible women, at least 91% received radiotherapy, 78% received chemotherapy, 82% received endocrine therapy, and 89% received anti-HER2 targeted agents. After adjustment for other treatment, lack of receipt of guideline-appropriate therapy was related to an increased risk of breast cancer death for endocrine (HR 1.76; 95% CI 1.09-2.84) and radiation therapy (HR 2.05; 95% CI 1.14-3.69). The few HER2-positive women not treated precluded further assessment. After accounting for endocrine and radiation therapy the survival disparity HR of 1.6 in Hispanic women was reduced to 1.57 suggesting only 2% of the disparity was due to differences in receipt of these treatments.
Conclusion: Limitations include likely undercounts of appropriate therapy, thus proportions cited are minimal estimates. Appropriate therapy includes only documented receipt as therapy completion could not always be assessed. Hispanic women have a disproportionately higher breast cancer mortality despite apparently receiving adjuvant therapies to a similar degree as non-Hispanic white women. Equalizing standard of care and attempting to reduce treatment disparities may not be sufficient to address the disproportionate mortality in Hispanic women.

Abstract
INTRODUCTION High-dose therapy with haematopoietic progenitor cell support has increasingly been utilised for patients with haematological malignancies. Peripheral blood is the stem cell source of choice, however, various mobilisation strategies are used by different centres. PATIENTS AND METHODS Over a 2-year period, 52 patients with non-Hodgkin's lymphoma (median age 47 years, range 16-64 years) underwent peripheral blood progenitor cell mobilisation using G-CSF alone (16 microg/kg/day). The harvest was considered successful if > or =1 x 10(6) CD34(+) cells/kg were collected by leukapheresis. The histological subtypes of non-Hodgkin's lymphoma comprised: follicular (24 patients), diffuse large B-cell (14 patients), lymphoplasmacytoid (four patients), mantle cell (three patients), lymphoblastic lymphoma (one patient) and small lymphocytic lymphoma/chronic lymphocytic leukaemia (six patients). The median interval from diagnosis of non-Hodgkin's lymphoma to mobilisation was 27 months (range 2 months to 17 years). The median number of prior treatment episodes was 2 (range 1-5); 26 patients had received fludarabine alone or in combination. At the time of peripheral blood progenitor cell mobilisation, 20 patients were in 1st remission and 32 were in > or =2nd remission; 30 patients were in partial remission and 22 were in complete remission; the bone marrow was involved in nine patients. RESULTS Peripheral blood progenitor cell mobilisation/harvest was unsuccessful in 19 out of 52 (37%) patients (mobilisation: 18, harvest: 1). The factors associated with unsuccessful mobilisation or harvest were: prior fludarabine therapy (P=0.002), bone marrow involvement at diagnosis (P=0.002), bone marrow involvement anytime prior to mobilisation (P=0.02), histological diagnosis of follicular, mantle cell, or lymphoplasmacytoid lymphoma, or small lymphocytic lymphoma/chronic lymphocytic leukaemia (P=0.03) and female gender (P=0.04). CONCLUSION Although peripheral blood progenitor cells can be successfully mobilised and harvested from the majority of patients with non-Hodgkin's lymphoma after treatment with G-CSF alone, the latter is unsuccessful in approximately one-third of patients. These factors should be taken into account when patients are being considered for high-dose treatment.

Abstract
Despite the large number of women in the healthcare field, healthcare management resembles other industries in its severe lack of women in upper-management positions and in the "glass ceiling" that contributes to this dearth. Although not enough has been specifically written on women healthcare managers, the author reviews what is available, along with some of the general management literature.

Abstract
At a time when all of healthcare is undergoing change and evolution, the healthcare education community has so far escaped intense public scrutiny. To remain valid, we must address the education and the reeducation of healthcare professionals. Baccalaureate health administration programs, in particular, can step in and respond to the changing needs of the industry, the market, and of healthcare professionals by creating articulation formats that provide flexible verti for associate degreed healthcare professionals. Such programs enable a diverse constellation of healthcare professionals to obtain the managerial and organizational skills that are cal and horizontal access key to career mobility in today's turbulent healthcare arena.

Abstract
Articles in the literature in the popular and professional journals and periodicals sustain the idea that significant barriers and a glass ceiling exist for women. While recognizing that overt and covert intentional discrimination may be a force in women's lack of career attainment, this work focuses on a network of semi-transparent societal and work world barriers which impede the career success of female healthcare managers.

Abstract
During a phase I clinical and pharmacologic trial, 26 patients with refractory solid tumors were treated with increasing doses of adozelesin by brief intravenous infusion every 3 weeks. Overall, adozelesin was well tolerated. The dose-limiting toxicity was myelosuppression, mainly thrombocytopenia and leukopenia. Nonhematologic toxicity was generally mild, with fatigue (36%), local reaction at the infusion site (24%), nausea or vomiting (20%) and hypersensitivity reaction (16%) being the most common adverse effects. There were no objective clinical responses. The maximally tolerated dose on this schedule was 188 micrograms/m2 with the recommended phase II starting dose being 150 micrograms/m2 on an every 3 week schedule. Adozelesin merits broad investigation at the phase II level.

Abstract
Patients with bilateral renal carcinoma or malignancy in a solitary kidney are best managed by radical nephrectomy with subsequent dialysis and transplantation. Because of the risk of recurrence of the tumour, the timing of the transplant procedure is important. We report on two patients with bilateral renal carcinoma who were subjected to radical nephrectomy and then managed with dialysis and transplantation within 6 months.

Abstract
A priming effect, increasing responsiveness of the nasal mucosa as measured by nasal patency or resistance, has been reported to occur after nasal challenge on successive days. Because it has been suggested that the priming effect may be of clinical importance, we have studied whether such an effect occurs during natural pollen exposure as measured by symptom-medication scores in 29 patients with ragweed rhinitis. By Wilcoxon's signed rank test, we compared the symptom-medication scores of patients during two 7-day periods, one early in the season and one later, in which the weekly pollen count was approximately 250 grains/m3; we also compared an early and late period during which the weekly pollen count was approximately 500 grains/m3. There were no statistically significant differences in scores between early and late seasonal periods at the same pollen count. We conclude that the priming effect is not a clinically significant phenomenon during natural pollen exposure in allergic rhinitis patients.

Abstract
Snoring was investigated in a survey of respiratory disease in Hispanic-Americans of a New Mexico community. A population-based sample of 1222 adults was studied with questionnaires and measurements of height, weight, and blood pressure. The age-adjusted prevalence of regular loud snoring was 27.8% in men and 15.3% in women. Snoring prevalence increased with age and obesity in both men and women. Cigarette smoking was also associated with snoring, but chronic obstructive lung disease and alcohol consumption were not. Snorers more frequently had hypertension, ischemic heart disease, and excessive daytime sleepiness. In contrast to other studies, after adjustment for confounding factors, there was no effect of snoring on hypertension (odds ratio, 1.0; 95% confidence interval, 0.7 to 1.5), but an effect on myocardial infarction was still demonstrable (odds ratio, 1.8; 95% confidence interval, 0.9 to 3.6). The association of snoring with sleepiness suggests that respiratory disturbance of sleep related to upper airway obstruction, such as sleep apnea, occurs more frequently in snorers in this population.

Abstract
To examine ethnic differences in infectious disease-related mortality in New Mexico's American Indian, Hispanic White and other White populations, we analyzed vital records data from 1958 to 1987. We found that for most infectious causes, American Indians had the highest mortality rates, followed by Hispanics. The state's minority populations remain at increased risk for infectious disease mortality.

Abstract
rTNF was administered to 28 patients with advanced metastatic cancers by continuous intravenous infusion for 5 consecutive days every 2 weeks. The dose levels were 30, 40, 70, 110, 180 and 290 micrograms/M2/day. Groups of 3 patients were started at each successive dose level and then on subsequent courses treated with the next dose level through 4 escalations as tolerated. Tumor types were: colon cancer 14; adenocarcinoma of unknown primary, 2; renal cancer, 2; leiomyosarcoma, 2; lung cancer, 1; prostate cancer, 1; thymona, 1; bladder cancer; 1; parotid, 1; Kaposi's sarcoma 2; ovarian 1. Toxicities included fever and chills (usually within the first 8 hours of infusion), fatigue, headache, decreased performance status, hypotension and CNS. All patients experienced leukopenia and thrombocytopenia within 24 hours or less after start of infusion with return of baseline by 72 hours after rTNF was stopped. The fall in these counts averaged 50% and was not dose related. No major changes in liver or renal function, coagulation or blood lipids were seen. Major dose limiting toxicities were fatigue, confusion, thrombocytopenia, seizures, hypotension and decreased performance status. NK cell activity measured against K562 target cells was augmented from about 30% target cell lysis to about 70% target cell lysis over the first 7 days of treatment. Two patients, both with metastatic colon cancer showed transient, objective tumor regression which did not qualify as a partial response. One patient with ovarian cancer had a stable partial response but progressed after 13 courses of treatment. Continuous infusion of TNF can be safely administered to patients with a maximum tolerated dose of only between 30 and 40 micrograms/M2/day.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To describe trends in mortality from ischemic heart disease in New Mexico's Hispanic, American Indian, and non-Hispanic white populations, we used vital records data collected from 1958 through 1982. We calculated age-adjusted and age-specific mortality rates for ischemic heart disease for each of the state's principal ethnic groups. Death certificate data were used in combination with population estimates based on the censuses of 1960, 1970, and 1980. Age-adjusted mortality rates for ischemic heart disease among Hispanics, American Indians, and non-Hispanic white men were consistent with nationwide patterns of rising mortality rates during the 1960s followed by declining rates. Mortality rates from ischemic heart disease in all three ethnic groups in New Mexico were lower than national rates for whites. Rates for Hispanics in New Mexico were lower than for non-Hispanic whites; rates for American Indians were the lowest among the three groups. These data support previous observations that Hispanics and American Indians in the Southwest are at decreased risk for mortality from ischemic heart disease in comparison with U.S. whites.

Abstract
A recent survey of 670 CEOs revealed that 51 percent had already established physician referral services and 65.2 percent were involved in various activities geared towards strengthening physician relations, one of which was increasing staff personnel to perform these functions (Hospitals March 20, 1987). It is apparent that PRPs have gained wide acceptance and have proved helpful in bettering relations between hospitals and physicians and, at the same time, helped both of them to offer better health care to the public. These programs can be very beneficial to patients and help make the referral system more organized and formal, based on relevant data and knowledge of patients' needs and physicians' needs, qualifications and specialties. Current literature on PRPs is appearing more frequently. Enough hospitals have begun such programs that a new PRP director should be able to research the subject quite thoroughly and become familiar with the possible strengths and weaknesses. Software for PRPs has been developed by various companies which should make the program more useful in terms of data collection, follow-up and provision of feedback. In my opinion PRPs are needed, and if they are marketed correctly, to the physicians initially and then to patients, such programs will prove extremely advantageous to all involved: hospitals, physicians and patients.

Abstract
The New Mexico Melanoma Registry and New Mexico Tumor Registry identified 81 cases of melanoma involving the skin and mucous membranes of Hispanics. The clinical and pathologic characteristics of these tumors were compared with those observed in whites. The frequency of melanoma in Hispanics appears to be no more than a sixth of that observed in whites. Female patients were more prevalent within the Hispanic population. The median patient age at diagnosis was similar in Hispanics and whites. A much larger proportion of melanomas in Hispanics occurred on the palms, soles, and in subungual regions. Acral lentiginous melanomas were correspondingly more frequent among Hispanics, as was mucous membrane melanoma. Melanomas arising from the palms, soles, subungual regions, and mucous membranes tended to be advanced in stage, to occur in older individuals, and to metastasize. These cases explain the generally poorer prognosis for Hispanic patients compared with whites. The epidemiology of melanoma relevant to these findings is discussed.

Abstract
Compound 48/80 inhibited phosphatidylinositol-specific phospholipase C activity from human platelets. Whereas 1 microgram/ml of compound 48/80 slightly stimulated Ca2+-dependent phospholipase A2, higher concentrations led to dose-dependent inhibition of this platelet enzyme. This biphasic effect was confirmed with phospholipases A2 purified from rat liver and human synovial fluid. The aggregation of human platelets induced by ADP and PAF-acether was inhibited by compound 48/80, whereas the aggregation induced by ionophore A23187 was not modified by this compound. These results demonstrate that the inhibition of platelet aggregation by compound 48/80 is not due solely to effects on calmodulin as previously reported, but that inhibition of phospholipases and probably arachidonate mobilization may also be involved.

Abstract
All forms of skin cancer are uncommon among southwestern American Indians. The estimated average annual incidence of melanoma is approximately 1 per hundred thousand population or less than one tenth of that currently reported for Anglos (non-Hispanic whites) residing in the same region. This study correlates the clinical and pathologic features of melanoma in 18 American Indian patients. A marked predilection for palms, soles, and subungual locations was displayed. Additionally, three patients presented with mucous membrane primaries and two with ocular melanomas. Advanced disease stage at diagnosis was common. The protective influence of natural pigmentation in skin cancer is discussed.

Abstract
Old female rats exhibiting either the constant vaginal estrous (CE) or the prolonged diestrous (PD) state were given lergotrile mesylate (LM). Treatment with 4.5 mg/kg daily significantly reduced prolactin (PRL) levels in both groups. The basal luteinizing hormone (LH) levels were not altered. In the CE group, LM treatment produced a single prolonged cycle, with the reemergence of the CE state. However, in the PD group, the rats exhibited several regular cycles during the treatment period. Several of these rats also showed evidence of having an LH surge during the reinduced cycle. These results suggest that high PRL levels may be a causative factor with respect to acyclicity in the PD rats, but PRL does not seem to be a major contributor to acyclicity in the aged CE rat.

Abstract
The drawing of blood by orbital sinus puncture (OSP) under ether anesthesia is known to produce a marked increase in serum prolactin (PRL levels in young cycling female rats. The effect of this stressful procedure on PRL release was compared in young and aged female rats. Nonstressed PRL levels were obtained from blood drawn by decapitation. Whereas OSP with a one-minute ether exposure induced a marked increase in PRL levels in young rats on all days of the estrus cycle, older cycling female rats on the day of diestrus -1 and aged rats exhibiting prolonged diestrus (PD) showed virtually no increase above nonstressed levels. However, increasing the ether exposure time to five minutes did produce a rise in PRL levels. Old cycling female rats on the day of estrus and aged rats exhibiting constant estrus (CE) did show a PRL increase comparable to that seen in young animals. Ovariectomy (OVX) completely abolished the stress response seen in aged CE rats. The response, though markedly decreased, was still present in young ovariectomized rats. These experiments show that the stress-induced rise in PRL promoted by OSP under either anesthesia is markedly diminished in aged rats exhibiting a diestrus state. The attenuated response seen in these rats is believed due to factors characteristic of the diestrous state of aging.

Cathodal (-) iontophoresis of 9-beta-D-arabinofuranosyl-adenine 5'-monophosphate (vidarabine monophosphate; Ara-AMP) was performed once daily for 3 days for the treatment of experimental herpes simplex virus type 1 (HSV-1) keratitis in rabbit eyes, and the therapeutic efficacy was compared with that of topical treatment of Ara-AMP and idoxuridine (IDU) administered five times daily for 4 days. With the treatment initiated 24 hr after viral inoculation, Ara-AMP cathodal iontophoresis resulted in significant suppression of epithelial and anterior segment disease processes. Topical IDU (0.5%) or Ara-AMP (10%) also significantly improved the disease process when compared to the placebo-treated group; however, iontophoresis of Ara-AMP resulted in a more marked improvement. Slit-lamp examination indicated that iontophoresis did not cause any observable pathologic changes in corneal epithelium, stroma, conjunctiva, or iris of rabbit eyes. This experiment suggests that iontophoresis of Ara-AMP is a safe and effective approach for preventing the development of herpes simplex keratitis in rabbits.
