Abstract
BACKGROUND Monoclonal antibodies, such as cemiplimab and pembrolizumab, against the programmed death receptor (PD)-1 have become the current standard of care and first-line treatment of advanced cutaneous squamous cell carcinoma (cSCC), proving remarkable clinical benefit and acceptable safety. OBJECTIVES To assess efficacy and safety of the anti-PD-1 antibody nivolumab in patients with locally advanced and metastatic cSCC. METHODS Patients received open-label nivolumab 240 mg intravenously every 2 weeks for up to 24 months. Patients with concomitant haematological malignancies (CHMs), either non-progressing or stable under active therapy, were eligible for inclusion. RESULTS Of 31 patients with a median age of 80 years, 22.6% of patients achieved an investigator assessed complete response, resulting in an objective response rate (ORR) of 61.3% and a disease control rate (DCR) of 64.5%. Progression-free survival (PFS) was 11.1 months, and the median overall survival (OS) was not reached after 24 weeks of therapy. Median follow-up was 23.82 months. Subgroup analysis of the CHM cohort (n = 11; 35%) revealed an ORR of 45.5%, a DCR of 54.5%, a median PFS of 10.9 months, and median OS of 20.7 months. Treatment related adverse events were reported in 58.1% of all patients (19.4% grade 3, the remaining grade 1 or 2). PD-L1 expression and CD-8+ T-cell infiltration did not significantly correlate with clinical response, although a trend towards a shorter PFS of 5.6 months was observed with PD-L1 negativity and low CD8+ intratumoral infiltration. CONCLUSION This study demonstrated robust clinical efficacy of nivolumab in patients with locally advanced and metastatic cSCCs and a tolerability comparable to data of other anti-PD-1 antibodies. Favourable outcomes were obtained despite involving the oldest hitherto reported study cohort for anti-PD-1 antibodies and a significant proportion of CHM patients prone to high risk tumours and an aggressive course otherwise typically excluded from clinical trials.

Abstract
INTRODUCTION A novel referral pathway for exhibited breast symptom (EBS) referrals to manage increasing referrals of urgent suspected cancer (USC) was implemented in our trust. We report on the safety and effect on compliance with the 2-week-wait rule (2WW). METHODS A single-centre longitudinal observational study included all patients referred to a UK breast unit during 13 May 2019 to 27 March 2020 (period 1) and 8 February 2021 to 31 January 2022 (period 2). USC referrals were assessed in a one-stop clinic (red flag clinic [RFC]); EBS referrals were assessed in a new clinic in which clinical evaluation was performed and imaging occurred subsequently (blue flag clinic [BFC]). Patients were followed up to determine the symptomatic interval cancer rate. RESULTS There were 9,695 referrals; 1,655 referrals (17%) were assessed in the BFC after 63 exclusions. Some 95.9% of patients had a benign clinical examination (P1/P2), 80.1% had imaging (mammogram or ultrasound) and 4% had a tissue biopsy. In total, 16/1,655 (0.97%) BFC patients and 510/7,977 (8.2%) RFC patients were diagnosed with breast cancer (breast cancer detection rate). Some 1,631 patients (with 1,639 referrals) were discharged and followed up for a median of 17 months (interquartile range 12-32) with one subsequent cancer diagnosis (symptomatic interval cancer rate, 0.06%). Implementation of the BFC pathway increased 3-month average trust performance of USC referrals with 2WW standard from 8.5% to 98.7% (period 1) and from 30% to 66% (period 2). CONCLUSIONS The BFC pathway for EBS patients is safe and implementation led to improvement against the 2WW target for USC referrals, ensuring resources are prioritised to patients with the highest likelihood of breast cancer.

Abstract
Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance of studied climatic, host-related and geographic factors on differences in tree-associated communities. Mean annual temperature, phylogenetic distance between hosts and geographic distance between locations were the major drivers of dissimilarities. The increasing importance of high temperatures on differences in studied communities indicate that climate change could affect tree-associated organisms directly and indirectly through host range shifts. Insect and fungal communities were more similar between closely related vs. distant hosts suggesting that host range shifts may facilitate the emergence of new pests. Moreover, dissimilarities among tree-associated communities increased with geographic distance indicating that human-mediated transport may serve as a pathway of the introductions of new pests. The results of this study highlight the need to limit the establishment of tree pests and increase the resilience of forest ecosystems to changes in climate.

Abstract
Adults of the large pine weevil (Hylobius abietis) cause serious damage to coniferous seedlings and are among the most important forest pests in Europe. Seedling protection by chemicals is gradually being restricted or banned for environmental reasons, and non-chemical alternatives are therefore needed. In this 3-year study, we compared the following five treatments for protecting Norway spruce seedlings against H. abietis in the Central European mountains where the weevil is especially abundant: alpha-cypermethrin sprays (the only chemical treatment); coating with sprayed glue (Vermifix); wax coating with C and F types (Norsk Wax); and physical protection with collars. The same block design was set up at a clear-cut site and at a nursery site to compare seedling mortality and wax quality under “wild conditions” with pests and under “ideal conditions” without pests. Repeated application of alpha-cypermethrin was the most effective and least expensive method to protect seedlings against H. abietis. Among the four non-chemical methods, repeated application of glue was the most effective. Because collars were moderately effective but not cost-effective, we do not recommend the use of collars. Wax was inexpensive and environmentally safe but protected seedlings for only 1 year; the newer F type of wax performed better than the C type of wax, and perhaps the F type can be improved. In general we found that seedlings at sites with high numbers of H. abietis require protection for at least 3 years. We conclude by providing an overview of all methods currently available for managing H. abietis in forests.

Abstract
International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated fungi and insects is needed. We present records of endophytic fungi and insects in twigs of 17 angiosperm and gymnosperm genera, from 51 locations in 32 countries worldwide. Endophytic fungi were characterized by high-throughput sequencing of 352 samples from 145 tree species in 28 countries. Insects were reared from 227 samples of 109 tree species in 18 countries and sorted into taxonomic orders and feeding guilds. Herbivorous insects were grouped into morphospecies and were identified using molecular and morphological approaches. This dataset reveals the diversity of tree-associated taxa, as it contains 12,721 fungal Amplicon Sequence Variants and 208 herbivorous insect morphospecies, sampled across broad geographic and climatic gradients and for many tree species. This dataset will facilitate applied and fundamental studies on the distribution of fungal endophytes and insects in trees.

Abstract
Diverse communities of bacterial endophytes inhabit plant tissues, and these bacteria play important roles for plant growth and health. Cherry laurel (Prunus laurocerasus L.) is a broadleaf evergreen shrub that is widely grown in temperate zones for its ornamental and medicinal properties, however virtually nothing is known about its associated bacterial community. In this study, we analysed the matured one-year-old leaves of this plant using Illumina-based 16S rRNA gene metabarcoding to reveal the community structure of endophytic bacteria and understand its shifts during the seasonal transition from winter dormancy to a spring vegetative state. The overall community was composed of four dominant phyla (Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes). Corynebacterium, Acinetobacter, and Chryseobacterium genera were the most prevalent bacteria, comprising 13.3%, 6.9%, and 6.8% of the amplicon sequence variants (ASVs), respectively. The ASV richness and diversity increased significantly in May as compared to other sampling months (February, March, and April). We observed high variation in the overall community structure of endophytic bacteria among collection dates. The variation was only reflected by a few core community members, suggesting that the changes of the endophytic community during winter/spring seasonal transition are mostly associated with the less abundant community members. We identified biomarker taxa for late winter, mid spring, and late spring collection dates. This study is the first one to report on the diversity and composition of bacterial endophytes in the leaves of cherry laurel and its shifts across the dormancy-to-vegetative seasonal transition.

Abstract
We evaluated the presence and impact of Entomophaga maimaiga on both target and non-target phytophagous larvae. All six study plots, with low gypsy moth population density, were situated in Central and Southeastern European oak forests and E. maimaiga had previously been reported from these plots. Totally, 45 of 4,045 (1.13%) collected non-target larvae died due to fungal infections. No non-target insect specimen was infected by E.maimaiga, although the presence of the pathogen could not be fully excluded in three cadavers. Out of 1,780L.dispar larvae collected, 15individuals (0.84%) were infected by E.maimaiga.

Abstract
Neozygites osornensis is a recently described aphid pathogen characterized by morphological criteria and compared with two morphologically close taxa, Neozygites cinarae and Neozygites turbinata. Neozygites species are traditionally classified based on morphological characteristics and molecular data that would confirm these taxa and permit investigation of their phylogenetic relationships are scarce. In this study, we successfully evaluated a genetic variation within partial 18S rDNA sequences among the three Neozygites species and supported the recent erection of N. osornensis as a new species. A phylogenic analysis was also included to support our results.

Abstract
An entomophthoralean fungus causing epizootics in populations of the cypress aphid, Cinara cupressi Buckton, in Chile is described as a new species, Neozygites osornensis Montalva et Barta. The aphid pathogen is described based on morphological characters. An exhaustive description, illustrations and a comparison with closely related species are provided. The fungus differs from similar Neozygites species by smaller hyphal bodies, nuclei, primary conidia, capilliconidia and capilliphores and by noticeably different shape of capilliconidia. A key to aphid-pathogenic species of Neozygites is also included.

Abstract
Nineteen anestrous bitches with a mean of 22 kg body weight and ranging from 2 to 4 years of age were induced to exhibit estrus and ovulate using PMSG and HCG. Twelve days after the first day of estrus, bitches were assigned to four treatment groups. Group (A) consisted of six bitches, Group (B) of five bitches and Groups (C) and (D) of four bitches each. At this time, bitches in Groups (A), (B) and (C) were laparotomized and those assigned to Groups (A) and (B) were bilaterally hysterectomized leaving the cervix and oviducts intact. Although bitches in Group (C) were laparotomized, they were not hysterectomized. Group (D) bitches were not subjected to any surgical procedures. Homologous uterine extract was prepared from each bitch in Group (A) and administered intramuscularly beginning on day 25 (day 0=first day of estrus) and continued every other day for 61 days post-estrus. Bitches in Group (B) were similarly injected with equal volumes of 0.9% saline. Blood samples, obtained prior to laparotomy and every other day for 85 days thereafter, were assayed for plasma progesterone concentrations using radioimmunoassay. One bitch in each of Groups (A) and (D) did not form luteal tissue following treatment with PMSG and HCG although both bitches exhibited estrus following treatment. All other bitches showed an increase in progesterone levels (4 to 19 ng/ml) between the first day of estrus and 10 days post-estrus. Thereafter, progesterone levels progressively declined in all groups with levels below 1 ng/ml between 38 to 40 days post-estrus. Results of this study suggested that CL formed in the bitch following PMSG and HCG treatment have a reduced function compared to non-induced CL of a normal, non-fertile estrous cycle. Such premature CL regression appears to be independent of the presence or absence of the uterus.

Abstract
The effect of low dose T-2 toxin was investigated in chicken, duck and goose. The purpose of the present study was to investigate the effect of T-2 toxin on the lipid peroxidation and on the activity of glutathione redox system (amount of reduced and oxidised glutathione and the activity of glutathione peroxidase) in blood and liver. The treatment lasted days and two samples were taken, first at the time of lowest feed intake and second when the intake was the same as the control. It was found, that lipid per oxidation as detected by the amount of malondialdehyde increased in all of the species and tissues but the changes varied by species. The most sensitive species was goose followed by duck and chicken, and the most sensitive tissue was the liver followed by blood plasma and red blood cells.

Abstract
60% of relapses of rectal cancer after abdominoperineal resection occurs at the site of the surgical intervention. Early detection of these recurrent tumours is vital. Among the up-to-date imaging systems CT is the most sensitive method in diagnosis of pelvic tumours. Despite the accurate imaging diagnosis the nature of lesions remains sometimes ambiguous. 11 CT guided biopsies and 2 punctures were performed because of suspected local recurrence or abscess. As a result of biopsies, local recurrence was histologically proven in 6 cases, fibrosis in 4, inflammatory disease in 1. Both punctures revealed the cytological diagnosis of abscess. There were no complications. The interventions were carried out in prone position through the greater sciatic foramen. In the knowledge of the exact anatomy of this region, the procedure can be performed safely by CT guidance and a correct diagnosis can be achieved.

Abstract
New Zealand White rabbits (6 males and 6 females) were fed a diet of high lipid peroxide content (peroxide value: 249.05 meq/kg fat) for 21 days. Twelve rabbits served as controls (peroxide value: 40.3 meq/kg fat). The lipid peroxide loading did not cause clinical signs. The rate of lipid peroxidation, as measured on the basis of thiobarbituric acid reactive substances (TBARS), was significantly (P < 0.05) higher in all of the investigated tissues, in the following order: liver > red blood cells (RBC) > blood plasma. Reduced and oxidised glutathione content was higher in the blood plasma (P < 0.01) and liver (P < 0.001) of rabbits exposed to the peroxide load. Lipid peroxide loading decreased the activity of glutathione peroxidase in the blood plasma, RBC haemolysate and liver and that of glutathione reductase in the liver. The amount of cytochrome P450 (both CO- and metyrapone-reduced) and the activity of cytochrome c (P450) oxidoreductase in the microsomal fraction of the liver homogenate were also lower in the group exposed to lipid peroxide load. Subchronic alimentary lipid peroxide loading in the presence of sufficiently high levels of antioxidants in the complete feed was found to increase the rate of lipid peroxidation and markedly lower the activities of both the glutathione and xenobiotic transforming enzyme systems without causing any clinical signs of toxicity.

Abstract
Oestrus cycles were investigated in seven polar foxes: the investigation consisted of evaluation of clinical symptoms of heat (vulva enlargement), measurement of vaginal mucus electrical resistance and determination of progesterone concentrations in the blood plasma of foxes; the objective was to determine optimum insemination time. The females were inseminated with fresh semen intravaginally by means of a pseudopenis, a day following the record of maximum electrical resistance of vaginal mucus and at the minimum progesterone concentration in blood plasma of 30 ng.ml-1. The females were reinseminated on the following day. The insemination dose had a volume of 1 ml with sperm concentrations of 150.10(6). Clinical symptoms of heat were observed in six out of the seven test foxes. Heat detection by means of measuring vaginal mucus electrical resistance was successful also in six females. Progesterone test enabled to detect heat in five females. Out of six inseminated females, five foxes became pregnant (83.3%) and a total of 33 cubs were born; this is 5.5 cubs per female.

Abstract
The ultrasonographic diagnosis of intussusception may be a recent complementation of X-ray fluoroscopy controlled hydrostatic desinvagination. Ultrasound is also useful in follow-up of the effectiveness of conservative management. By presenting their experience gathered by successful treatment of one case, the authors' aim is to contribute to the spread of this method.

Abstract
Hyperthermia modulated the cytotoxic activities of murine macrophages cocultured with EMT-6 tumor cells, altered the production of the monokines RIF (respiratory inhibition factor) and FeRF (iron-releasing factor) by these effector cells, and perturbed the activities of these monokines against EMT-6 cells. Cytotoxic activities of heated murine macrophages activated by Bacillus Calmette-Guérin were inhibited by heat doses of 40.5 degrees C for greater than or equal to 1 h if heating preceded triggering by the endotoxin lipopolysaccharide; however, cytotoxic activities were better retained if triggering preceded heating by 2 h. Treatment-sequence dependencies were also found in the secretion of some monokines that participate in these macrophage cytotoxic effects. Secretion of both RIF and FeRF by macrophages was slightly augmented or at least better retained if triggering of macrophages occurred several hours before heating for 1 h at 40.5-43 degrees C or for 24 h at 39-40.5 degrees C. If heating was nearly simultaneous with triggering or preceded it by several hours, there was a dose-dependent decrease in monokine secretion. The sensitivity of tumor cell targets to these monokines was also modified by the treatment sequence. When EMT-6 cells were treated with RIF- or FeRF-containing macrophage conditioned supernatants 1 h before heating at 40.5-43 degrees C, the RIF-treated cells became sensitized and the FeRF-treated cells retained better cytotoxic response than if cells had been treated 1 h after heating. Chronic heating for 24 h at 39-40.5 degrees C showed less dependence of tumor cell response on treatment sequence. Similar observations have recently been made in our laboratory for the interaction of tumor necrosis factor cytotoxic pathways with hyperthermia (Klostergaard et al., J. Biol. Response Modif., in press, 1989; Tomasovic et al., Int. J. Hyperthermia, in press, 1989). Those results and the present observations with the monokines RIF and FeRF support our hypothesis that the cytotoxic actions of macrophages and the cytotoxicity of endogenously added monokines can be augmented by appropriately constructed sequences combining hyperthermia with either macrophage priming/triggering or monokine treatment of tumor cells.

Abstract
Post-operative neurosonography - through calvarial defect. 9 patients were examined by post-operative high resolution real-time ultrasound, using an operative calvarial defect. The findings of 2 patients are analysed in details. The authors have found good agreement with computed tomography, with other imaging methods and pathology as well. They suggest sonographic examination as a first step in the follow-up control of the pathological processes in patients with burr holes.

Abstract
A method has been developed for the collection of ejaculate from anaesthesized dog foxes. General anaesthesia was produced by inhaling 3 to 5% narcotan mixed with oxygen, the inhalation rate being two litres per minute. An electroejaculator with a bipolar electrode, introduced in the rectum, was used for the electrostimulation of ejaculation. The voltage needed to produce the ejaculation effect and the number of impulses depended on the individuality of the foxes. The average amount of ejaculate per one collection was 0.86 ml, the sperm motility percentage was 74.80% sperm concentration was 270.62 x 10(3) spermatozoa per mm3, and the average pH value was 6.87.

Abstract
Hyperthermia in the therapeutic (greater than or equal to 42-43 degrees C) and febrile (less than or equal to 39-40.5 degrees C) ranges modulated the cytotoxic activities of macrophages cocultured with tumour cells and of the monokine tumour necrosis factor (TNF) against tumour cells. These modulatory interactions had clear treatment-sequence dependencies, and some sequences markedly augmented cytotoxic activities. Heated murine bacillus Calmette-Guerin-activated macrophages retained their cytotoxic activities better in coculture with unheated tumour cells if triggering with the endotoxin lipopolysaccharide preceded 1 h of heating at 42 or 43 degrees C than they did if heating to the same extent was concomitant with, or preceded, triggering. Retention of cytotoxicity in coculture during 24 h of 39 or 40.5 degrees C heating was less dependent on pre-heating triggering. The triggering/heating sequence also had modulatory effects on the secretion by heated macrophages of TNF which is involved in cytotoxic manifestations in coculture. Production of TNF by macrophages heated for 1 h at 40.5-43 degrees C or 24 h at 39 or 40.5 degrees C was augmented 1.5- to 6-fold (depending on the heat dose) when triggering preceded heating, whereas sequences in which heating was concomitant with triggering or preceded triggering were detrimental to TNF secretion. Profound treatment-sequence dependencies were also seen when timing of the addition of recombinant human TNF was varied in relation to the heat treatment of tumour cells. Sensitization of TNF-responsive L-929 and TNF-resistant EMT-6 tumour cells occurred if monokine addition preceded heating, whereas the reverse treatment-sequence reduced or eliminated sensitization. Both tumour cell types were also sensitized to TNF if monokine treatment preceded 24 h heating at 40.5 degrees C. These results support the hypothesis that appropriately constructed sequences for either macrophage priming/triggering or monokine treatment of tumour cells, combined with hyperthermia, could augment the cytotoxic actions of macrophages and the cytotoxicity of endogenously added monokines.

Abstract
Vital dye uptake and postfixation dye assays have recently been used to examine the interaction between short-term (24-48 h) exposures to the monokine, tumor necrosis factor (TNF), and hyperthermic treatments with the finding that synergistic increases in cytotoxicity occurred. However, survival measured by these short-term dye assays is not necessarily closely related to eventual loss of clonogenic capacity. Treatment-induced growth delays, delayed cytotoxic effects, or perturbations of vital dye sequestration mechanisms could result in a different measurement of surviving fraction than given by a clonogenic assay. In this study we directly compared the neutral red vital dye uptake and clonogenic survival assays and confirmed in both assays that TNF-sensitive (L-929) and TNF-resistant (EMT-6) phenotypes show greatly reduced survival when treated with combined recombinant human TNF (1.0-0.0005 micrograms/ml) and hyperthermia (1-2 h at 43 degrees C). Moreover, we confirmed that sensitization of the TNF-resistant EMT-6 cells was largely dependent on monokine treatment before hyperthermia and was reduced by the reverse sequence. The greatest sensitization of TNF-responsive L-929 cells also occurred when TNF treatment preceded heating. These results for clonogenic survival are consistent with the hypothesis that hyperthermia used in combination with TNF in vivo is more cytotoxic than TNF or hyperthermia separately.

Abstract
The fertility of male coypu sperm following seminal vesicle extirpation was investigated using the penetration test into the egg of Syrian golden hamster (Mesocricetus auratus). Ejaculates were obtained from five males by means of electro-ejaculation under halothane narcosis. The results of the zona-free hamster eggs (ZFHE) penetration test showed that the ejaculates of all the surgically treated coypu males were fertile and that ZFHE value fluctuated from 54 to 76.6%. The results obtained in experiments with natural mating revealed that the extirpation of male coypu seminal vesicles did not affect their fertility. In total 47 foetuses were found post mortem in ten coypu females covered by surgically treated males, which on average represented 4.7 foetuses per female.

Abstract
Tumor necrosis factor (TNF) production by human peripheral blood monocytes and murine bacillus Calmette-Guerin-activated peritoneal macrophages was strongly influenced by acute hyperthermia. If hyperthermia was administered simultaneously with or preceding lipopolysaccharide triggering, production was severely ablated by 42 degrees and 43 degrees C treatments; however, if triggering preceded heating by at least 90 min, production was either unaffected or markedly enhanced. A somewhat similar pattern was reflected with chronic heating. TNF production by murine macrophages was inhibited with 39 degrees C heating and completely blocked by 40.5 degrees C treatment, if triggering coincided with the initiation of hyperthermia. However, augmentation of production occurred with either of these temperatures if triggering preceded hyperthermia by as little as 90 min. Human monocytes demonstrated greater resistance to the deleterious effects of coincident triggering and heating with respect to TNF secretion than the rodent effectors, but the response was otherwise very similar. The TNF-sensitive phenotype of the L929 cell could be augmented by chronic or acute hyperthermia, markedly so with a 43 degrees C treatment. The TNF-resistant phenotype of the EMT-6 cell could be reversed by chronic heating at 40.5 degrees C, or by acute heating at 43 degrees C, but only if the latter followed TNF treatment. These results reflect important regulatory controls of TNF production and responses in tumor cells which are susceptible to hyperthermia manipulation.

Abstract
The fluctuations in the concentrations of progesterone in peripheral blood of three intact coypus and three coypus after natural mating were investigated for the period of four months. Immediately after mating the concentrations of progesterone are low (1.5-2.4 ng.ml-1), the maximum values reach the peak between the 14th and 15th week of gravidity (12.50-20.72 ng.ml-1), whilst there is almost no change in the intact females. On the last days of gravidity the values of progesterone decrease rapidly and they are very low on the day of parturition (1.0-2.5 ng.ml-1). The concentration of progesterone in the blood plasma of intact females in the test period is low (0.09-3.18 ng.ml-1).

Abstract
Sixteen bitches were treated with pregnant mare serum gonadotropin (PMSG; 44 IU/kg bwt) intramuscularly (i.m.) for nine consecutive days and each was given 500 IU HOG i.m. on the tenth day or on the first day of induced estrus (Day 0). On Day 12, each bitch was randomly assigned to three groups and treated as follows: Group 1-six bitches, each given 10 mcg GnRH i.m.once every 24 hr; Group 2-six bitches, each given 500 IU HOG i.m. once every 24 hr; and Group 3-four bitches, each given 5 ml 0.9% saline i.m. once every 24 hr. Treatments were continued until Day 55. Blood samples were obtained prior to treatment and every other day until Day 55. Plasma progesterone concentrations were determined by radioimmunoassay (RIA) and data arranged using a split-plot design, with treatment as the main plot and days of sampling as subplots. Analysis of data was by Duncan's Multiple Range Test and treatment-by-day interaction determined by the least-squares method. After treatment, progesterone concentrations from Group 2 were higher (P<0.05) than those of the other groups. A significant effect was seen on Day 20 (P<0.01), while on Day 50 the difference approached significance. These findings suggest that HOG is capable of stimulating the production of progesterone by induced CL in the bitch. However, neither HOG nor GnRH prevented premature regression of these induced CL. Results of this study suggest that premature luteolysis of induced CL is probably not due to lack of gonadotrophic support from either the hypothalamus or the anterior pituitary gland.

Abstract
Eleven adult Basenji dogs with immunoproliferative small intestinal disease (IPSID) were studied. Two items of history related to the digestive tract were characteristic: (i) chronic intractable diarrhea in most dogs, and (ii) progressive emaciation. Anorexia was intermittent in only a few dogs. In addition, skin lesions of various degrees of severity were observed, including alopecia of pinnae and ventrum, hyperpigmentation and hyperkeratosis of pinnae, and necrosis and ulcerations of margins of pinnae. The cause of the skin lesions was not determined; however, hypothyroidism did not appear to contribute to the skin changes. Standard hematologic and serum chemical values were not consistently abnormal. However, a poorly regenerative anemia, mild neutrophilia, and increased aspartate aminotransferase and alanine aminotransferase activities were generally observed in severely affected dogs. The Pelger-Huet anomaly was identified in dog 3. Maldigestion and malabsorption as determined by the N-benzoyl-L-tyrosyl-p-aminobenzoic acid and d-xylose test was documented to varying degrees in dogs with IPSID. Maldigestion was correlated with functional pancreatic exocrine insufficiency. Severe malabsorption was documented in only 3 dogs. Serum gastrin values were evaluated in these dogs because of a prior observation of parietal cell hyperplasia and gastric ulceration. Hypergastrinemia was documented in 3 dogs. Additional studies will be necessary to determine whether an acid hypersecretory state contributes to the pathogenesis of IPSID in Basenjis.

Abstract
A surgical approach that offered direct visualization and removal of the hypophysis was evaluated in 17 dogs. Ten of the dogs were euthanatized and used to identify reliable landmarks for the drill site in the basisphenoid bone to expose the hypophysis. The intersphenoidal suture was an accurate landmark in that 1 cm caudal to the intersphenoidal suture was determined to be the precise point for the center of the drill hole. The remaining 7 dogs were hypophysectomized, using this approach. The landmarks were accurate, the surgery had a high degree of safety, and all hypophyses were removed.
