Abstract
Immunological parameters were studied before and after phototherapy, with bright and dim light, in 38 individuals with a range of retrospectively reported seasonal changes in mood and behavior. There was a significant negative correlation between the degree of mood and behavioral difficulties in fall and winter (seasonality) and the total number of circulating natural killer cells. Changes in the numbers of circulating helper T cells correlated significantly with changes in mood following phototherapy. Moreover, mitogen-induced lymphocyte blastogenesis increased significantly after phototherapy, but there was no significant difference between the bright and dim light treatments. The results suggest that cellular immune function is associated with both seasonality and response to phototherapy.

Abstract
The in vivo effects of allogeneic granulocytes on the reconstitution of splenic and bone marrow CFUs and CFUc numbers were investigated using irradiated mice. When allogeneic granulocytes were intraperitoneally injected into irradiated BDF1 mice (260 rads), the reconstitution of CFUs in both spleen and bone marrow as well as the hematocrit were enhanced, while the reconstitution of splenic or bone marrow CFUc numbers was transiently suppressed and then enhanced. The magnitude of enhancement was dose-dependent. These results suggest that granulocytes injected into irradiated mice might act as enhancing effectors on the in vivo reconstitution of hemopoietic cells.

Abstract
One of the major obstacles facing radioimmunotherapy (RIT) is the lack of a device to measure directly tumor and normal tissue radiation absorbed dose. Calculations based on the clearance and imaging scans have several limitations; hence we design and fabricate a sheathed clinical thermoluminescent dosimeter (TLD) for the measurement of absorbed dose by implantation in humans. Preclinical studies are performed in nine normal rabbits. Complete blood count, body temperature monitoring, clinical observation and necropsy show no untoward effects from the TLD. Consistent bone marrow radiation doses are noted in the four rabbits receiving 131I-labeled monoclonal antibody A6H. By using up to 20 clinical TLDs in one sheath, it will be possible to determine macroscopic heterogeneities in organs undergoing RIT.

Abstract
It has been established in the experiment on rats exposed to a joint action of plutonium-239, hexachlorobutadiene and ++tributyl phosphate, that manifestations of disturbances from radiation and chemical factors which are more expressed under a joint exposure, are characteristic of the thymus gland damage pattern. As far as lymphocytes count in the organ is concerned, the effect of the joint exposure is no more than additive.

Abstract
Investigation of certain indices of immunity in 52 patients with lung cancer subjected to X-ray irradiation at stages of the surgical treatment under conditions of various kinds of anesthesia have shown that preoperative radiation therapy with the dose of 30 gr resulted in a considerable suppression of immunity indices at the preoperative period and aggravated immune depression following operative procedures. At the same time immune depressive reactions were found to depend on the kind of anesthesia.

Abstract
Forty dogs with spontaneous skeletal neoplasia were treated with 153Sm-EDTMP (ethylenediaminetetramethylene phosphonic acid). Both primary and metastatic lesions were treated. Two treatment regimes, a single (37 MBq (1.0 mCi)/kg dose or two 37 MBq (1.0 mCi)/kg doses separated by 1 wk) were tested. Response to treatment was varied. Large lesions with minimal tumor bone formation responded poorly, while primary lesions with substantial ossification usually exhibited a transient response. Small lesions with minimal lysis, metastatic lesions, and axial skeleton lesions generally responded well. The major adverse side effects of treatment were platelet and white blood cell count depression below baseline values for up to 4 wk (p less than 0.05). Minor depression of packed cell volume and transient elevation of serum alkaline phosphatase were also noted (p less than 0.05). No significant differences (p greater than 0.05) between the two treatment groups, either in treatment effect or undesirable side effects, were detected.

Abstract
Study of certain immune status indicators of medical roentgenologists has detected certain immunodeficiency associated with exposure to low doses of ionizing radiation. The number of T-lymphocytes has been noticed to be reduced, while the degree of reduction increases with age, duration of work in the sphere of radiation, and the value of the individual dose of radiation within a year. B-lymphocytes number is susceptible to changes in a smaller degree.

Abstract
Results of the analysis of changes in peripheral blood lymphocytes size under chronic exposure to external gamma radiation and pesticide chlorophos++ in combination and separately are presented. It has been found out that under exposure of animals to radiation or the pesticide it is small and big lymphocytes respectively which most significantly suffer quantitatively. Under the joint radiation ++-chemical exposure of the organism the number of both types of cells is reduced simultaneously.

Abstract
A study was undertaken to determine the degree of acute bone marrow and vital organs injury sustained when dogs were administered doses of 153Sm-EDTMP calculated to irradiate an acute bone lesion arising from cancer metastasis to a dose considered palliative or even therapeutic (20-160 Gy). The study revealed significant (p less than 0.05) temporary depression of the bone marrow in all doses in the therapeutic (greater than 40 Gy) range. Palliative (20 Gy) doses caused significant leukocyte depression but insignificant (p greater than 0.05) depression of platelet and packed cell volumes when compared to control animals. A mild transient rise in the levels of serum alkaline phosphatase occurred immediately following radioisotope administration. All hematologic parameters had returned to normal by six weeks after the last injection of radioisotope. The study indicates potential for this compound as a safe, therapeutic radiopharmaceutical for treatment of cancer bone metastasis.

Abstract
Eighteen patients with unresectable localized adenocarcinoma of the pancreas were treated by a combination of chemotherapy plus hyperfractionated radiation therapy to the pancreas for 4080 cGy with an additional 960 cGy to the pancreatic tumor and a surrounding margin. One hundred and twenty cGy were given twice daily 4 to 6 hours apart. High-energy photon or electron beams were used with treatment planning based on computed tomographic (CT) scans. Patients were given chemotherapy in the form of 5-fluorouracil (5-FU) at 350 mg/m2 on the first 3 and last 3 days of radiation therapy. On day 53, chemotherapy was given that included 600 mg/m2 IV of 5-FU, 1 gm/m2 of streptozotocin, and 10 mg/m2 IV of mitomycin C. The 5-FU and streptozotocin were repeated on days 60, 81, and 88, and the stretozotocin and mitomycin (SMF) cycles were repeated every 8 weeks until progression. Radiation toxicity was generally tolerable with one of 18 evaluable patients having severe nausea and vomiting and two of 18 patients having severe diarrhea. One patient had total liver failure and died 3 months after initiation of therapy. Six patients had severe hematopoietic toxicity during chemotherapy. Overall, the severe toxicity rate was higher (67%) than in previous studies. Median survival was 35 weeks, the 1-year survival rate was 39%, and the patient who survived the longest died at 68 months. Although this schedule of hyperfractionated radiation and chemotherapy was disappointing, combined experimental radiation approaches plus chemotherapy for localized unresectable adenocarcinoma of the pancreas deserve additional research.

Abstract
We have investigated the efficacy of standard conditioning regimens for bone marrow transplantation in depleting functional T lymphocytes in vivo and have compared it with the efficacy of the monoclonal antibody Campath-1G. Using limiting dilution techniques the frequencies of proliferating T cell precursors (PTL), cytotoxic T cell precursors (CTL-p), helper T cell precursors (HTL-p), and mature helper T cells (HTL) were determined before and after treatment. Both total body irradiation and combination chemotherapy with busulfan/cyclophosphamide were highly efficient at depleting PTL, CTL-p, and HTL-p (0-4 days) but spared HTL to a variable extent (0-99.5%). In the majority of patients treated with Campath-1G a similar degree of PTL, CTL-p, and HTL-p depletion was achieved, and, in addition, HTL were effectively removed (greater than 95.5%). These results suggest that Campath-1G could be successfully employed in depleting radio- and chemotherapy-resistant host T lymphocytes prior to T-depleted bone marrow transplantation.

Abstract
A considerable number of irradiated persons appeared as a result of the accident at the Chernobyl Atomic Power Station. Analysis of chromosome aberrations and detailed hematological investigations were performed in them. Relatively uniform affection of the hemopoietic tissue could be anticipated on the basis of the results of the cytogenetic analysis in most of these persons who had been exposed to radiation at doses that were critical for the development of the bone marrow syndrome. It made it possible to establish direct quantitative relationship between the indices of a postradiation curve of the time course of the neutrophil count in peripheral blood and the mean rate of dicentrics in lymphocytes for cases of relatively uniform irradiation and to plot prognostic curves of neutrophils for different frequencies of dicentrics.

Abstract
Naive CBA/Ca mice and CBA/Ca mice vaccinated 4 weeks previously with radiation-attenuated cercariae of Schistosoma mansoni were subjected to 550 rad of whole body (gamma) irradiation and then challenged 3 days later with normal cercariae. The perfusion recovery data showed that this procedure reduced the primary worm burden in naive mice by 22% and the challenge worm burden in vaccinated mice by 82%. Irradiation also ablated the peripheral blood leucocytes of both mouse groups by 90-100% at the time of challenge. Histological data revealed that such treatment caused a dramatic change in number, size and leucocyte composition of cutaneous inflammatory skin reactions that characterize challenged vaccinated mice and are known to entrap invading larvae; cutaneous eosinophils were preferentially abolished by this treatment. Polyvaccine mouse serum that conferred protection passively upon naive recipient mice, failed to protect naive/irradiated mice when administered by the same protocol. Distraction of macrophages by treatment of mice with silica did not affect the establishment of a primary worm burden and reduced the protection exhibited by vaccinated mice by only 16%. These data indicate that radio-sensitive cells are important to both innate and specific acquired resistance in this mouse model and that macrophages contribute only marginally to the expression of vaccine immunity.

Abstract
The share of lymphocytes with abnormal nuclei in the peripheral rat blood was found to increase during the first 24 h following irradiation with doses LD0, LD50, and LD100. With LD50 the index under study significantly varied in survived, died and control animals. It is suggested that the occurrence of abnormal nuclei in the peripheral rat blood is the result of the two processes, namely, the mitotic division and apoptotic death of cells.

Abstract
Ten pig-tailed monkeys (Macaca nemestrina) were subjected to 60Co radiation at a dose of 6.0-6.5 Gy and a dose rate of 1.2 Gy/min. Acute radiation sickness has developed in the monkeys causing their death on the 16-20 day. In spite of this, the initial reaction was weakly expressed and according to its manifestation it was impossible to evaluate severity and possible outcome of the lesion. At an early stage of the disease (6-24 hours) insufficient was uranin fluorescence in blood plasma, but more informative were the changes in adhesive properties of leukocytes the dynamics of lymphocytes (lymphopenia), reticulocytes (reticulocytopenia) and shifts in reticulograms (increased per cent of juvenile forms).

Abstract
Patients with locally advanced cervical cancer have a poor prognosis. The efficacy of radiotherapy is limited by the presence of large tumor volume and nodal disease. As cisplatin is a documented radiosensitizer and has activity in squamous cell carcinomas, a prospective study was designed to evaluate the toxicity and potential synergism of concurrent cisplatin (20 mg/m2 x 5 d every 21 days) and radiotherapy in locally advanced cervical cancer. Forty-three patients were studied, of which 14 were stage IB/IIA (bulky disease) and 29 were stage IIB/IIIB/IVA. Of the 32 evaluable patients, there were 29 complete responders. Of these 29 patients, 27 remain without evidence of disease, with a median follow-up of 12 months. There were no treatment-related deaths. Cisplatin and radiotherapy appear to be a well-tolerated and highly effective regimen for locally advanced cervical cancer.

Abstract
The effects of preoperative radiation plus surgical stress on immunity were examined in 29 patients with esophageal cancer, including 14 patients who experienced radiation therapy and 15 who did not, as well as 15 age-, sex- and body weight-matched control subjects. Absolute numbers of the total lymphocytes and OKT3 (all T cells), OKT4 (helper/inducer T cells) and OKT8 (suppressor/cytotoxic T cells) positive lymphocytes were almost the same in both patient groups before treatment. Both the in vitro response to phytohemagglutinin (PHA) and antibody dependent cell-mediated cytotoxicity (ADCC) were depressed in the patients when compared to the controls before treatment. Dual treatment of radiation and surgery led to a marked reduction of lymphocytes in the numbers and activities of PHA and ADCC, when compared to findings in the non-radiation group. Especially, the number of OKT4 positive lymphocytes and the OKT4 to OKT8 ratio decreased most and recovery was slow. While ADCC activity in the non-radiation group recovered at 28 postoperative days (POD), the response to PHA did not return to the pretreatment levels. Serum levels of IgG, IgM and IgA were within normal limits throughout the course of treatment. The B1 (all B cells) positive lymphocytes significantly decreased after the treatments. These results suggest that radiation plus surgery shifts the host immunity toward immunosuppression and induces a significant impairment of cellular immunity in patients with esophageal cancer.

Abstract
Bone marrow ablation using combined whole body hyperthermia (WBH), total body irradiation (TBI), and cyclophosphamide (Cy) was investigated in C3H f/Sed mice to demonstrate cytotoxic synergism between the three modalities. TBI was given on day 0. WBH treatment was for 1 hr at 41.8 degrees C, given in daily sessions for 1, 2 or 3 modalities. TBI was given on day 0. WBH treatment was for 1 hr at 41.8 degrees C, given in daily sessions for 1, 2 or 3 consecutive days following TBI. Total cyclophosphamide doses were 160 and 240 mg/kg given in 2 daily injections on days 1 and 2 following TBI. Polymorphonuclear leukocyte and lymphocyte numbers were determined by differential cell counts. The total peripheral blood cell counts were also determined. WBH alone, given in daily sessions for 3 days, did not reduce the total peripheral blood cell counts. However, when WBH was added to TBI (6.3 Gy) peripheral blood cellularity was reduced on day 2, but no significant heat/radiosensitization was evident after day 2. WBH (3 daily sessions) significantly reduced the peripheral blood cellularity and resulted in bone marrow ablation when it was combined with TBI and Cy. CY (160-240 mg/kg) combined with TBI (5.4 Gy) resulted in bone marrow ablation and subsequent death in 14-22% of mice treated; 60-100% of mice died from bone marrow ablation when WBH was added to TBI (5.4 Gy) and Cy (160-240 mg/kg). Femoral and vertebral tissue sections showed total loss of progenitor cells when WBH, TBI (5.4 Gy), and Cy (240 mg/kg) were combined whereas lessor treatment was associated with histologically verified reconstitution of progenitor cells inside the marrow cavities. These studies indicate that bone marrow ablation can be achieved when using WBH in combination with lower doses of TBI and Cy.

Abstract
The number of T- and B-lymphocytes of the peripheral blood was studied in 59 medical radiologists. A decrease in the number of T-lymphocytes was noted, its degree being associated with an individual annual dose of irradiation, the period of contact with radiation and age. The number of B-lymphocytes was changed to a lesser degree. It is assumed that a previously reported decrease in the body resistance to environmental hazards depends, to a certain extent, on immunodeficiency detected in this work as well as on the deficiency of metabolism of C and B1 vitamins reported earlier.

Abstract
The experiments on rats exposed separately and in combination to radiation and chemical substances showed that the time of body pesticide intake (the total dose) was the leading factor affecting the phagocytosis indices. A daily pesticide dose had a credible impact on some indices. The combined effect was formed primarily due to chemical compounds. In general the effect could be regarded as less than additive though at some time it was additive and more than that.

Abstract
Contrary to bone marrow exposure, microwave therapy of the thymus (80 mW/cm2) in induction sensitization results in inhibition of the production of IgE-antibodies to staphylococcus Cowan. The process, studied in experiment, rested on microwave induction of the function of IgE-antibody formation of T suppressors.
