Previously we revealed for the first time pain response exacerbation caused by inflammation in rats born to dams exposed to stress during pregnancy (prenatal stress). The present study is devoted to tinvestigation of prenatal stress effects on psychoemotional and tonic pain reactions in rat pups during the individual development period that is characterized with a dramatic reduction of the brain serotonin level. Effects of maternal buspirone before stress during pregnancy on functional indices of psychoemotional and tonic pain systems in the offspring were also investigated. Prenatal stress increased the number of pain patterns (flexing + shaking) during different phases of the time-course of formalin-induced pain in females and males to a greater extent in males. Prenatlly stressed rat pups of both sexes failed to show reliable changes in the index of psychoemotional behavior in the forced swim test. With the aim to decrease pain response exacerbation found in prenatally stressed offspring, pregnant dams were exposed to chronic injections of serotoninergic anxiolytic and antidepressant buspirone which is an agonist of 5-HT1A receptors; prenatal effect of buspirone on psychoemotional behavior in prenatally stressed rat pups was also evaluated. Maternal buspirone normalized pain behavior and decreased considerably the time of immobility, the index of depressive behavior in the forced swim test. The present results indicate analgesic and antidepressive effects of maternal buspirone in prenatally stressed 10-day old rat pups and demonstrate sexual dimorphism in effects of prenatal stress on the time-course of formalin-induced pain. Differences in effects of prenatal influences on pain respone during the interphase in males and females indicate earlier maturation of the descending serotonergic inhibitory system of afferent pain signals modulation in males than in females and demonstrate that 5-HT1A receptors are involved in this process.

Bulbous Tip

Plant stinging emergences exhibit functional similarities in that they all elicit a pain response upon contact. A stinging emergence consists of an elongated stinging cell and a multicellular pedestal (Fig. 1). A recent ultrastructural investigation of these structures has revealed the ontogeny and morphology of the stinging cells differs in representative genera in the four plant families which possess such structures. A unique feature of the stinging cell of Urtica dioica is the presence of a siliceous cell wall in the apical portion of the cell. This rigid region of the cell wall is responsible for producing the needle-like apparatus which penetrates the skin. The stinging cell differentiates the apical bulbous tip early in development and the cell continues growth by intercalary addition of non-silicified wall material until maturity.The uppermost region of the stinging cell wall is entirely composed of silica (Fig. 2, 3) and upon etching with a 3% solution of HF (5 seconds), the silica is partially removed revealing the wall consisting of individualized silica bodies (Fig. 4, 5).

Summary Aim: Rhenium-188-HEDP (188Re-HEDP) is an effective radiopharmaceutical for the palliative treatment of osteoblastic bone metastases. However, only limited data on its routine use are available and its effect on quality of life (QoL) has not been studied. Therefore, we evaluated the clinical benefit of 188Re-HEDP in routine clinical care. Patients and methods: Prostate or breast cancer patients with painful bone metastases receiving 188Re-HEDP as a routine clinical procedure were eligible for evaluation. Clinical benefit was assessed in terms of efficacy and toxicity. Pain palliation and QoL were monitored using the visual analogue scale (VAS), corrected for opioid intake, and the EORTC QLQ-C30 Global health status/QoL-scale. Thrombocyte and leukocyte nadirs were used to assess haematological toxicity. Results: 45 and 47 patients were evaluable for pain palliation and QoL, respectively. After a single injection of 188Re-HEDP, the overall pain response rate was 69% and mean VAS-scores decreased relevantly and significantly (p < 0.05). Repeated treatment resulted in similar pain response. The overall QoL response rate was 68% and mean Global health status/QoL-scores increased relevantly and significantly. Haematological side effects were mild and transient. Conclusion: The clinically relevant response on pain and quality of life and the limited adverse events prove clinical benefit of treatment with 188Re-HEDP and support its use in routine clinical care. Its effectiveness appears comparable to that of external beam radiotherapy.

Background: Prenatal antiepileptic drug exposure could demonstrate both congenital malformations and behavioral impairments in offspring. Objective: This study was performed to assess the effects of prenatal exposure to pregabalin (PGB) on pain response, anxiety, motor activity and some behavior of adult offspring rats. Methods: Pregnant Wistar rats received PGB (7.5, 15 and 30 mg/kg/ip) during embryonic days 9.5- 15.5. The pain response, anxiety-like behaviors, locomotor activity, motor balance and coordination and anhedonia of adult offspring were examined by tail-flick and hot plate test, open field test, elevated plus maze (EPM), beam balance test and sucrose preference test in their 60th day of life, respectively. Results: Prenatal exposure to PGB revealed significant dose-dependent reduction in pain sensitivity (increase in pain latency response) in the hot plate test, especially in females, while anxiety-like behavior assessed in EPM and open field significantly reduced in males. In the open field, locomotor activity reduced significantly after exposure to PGB 30 mg/kg and motor coordination decreased dose-dependently, especially in males. Anhedonia, as an indication of sucrose preference or pleasure response, was not changed. Conclusion: These findings suggest that prenatal PGB exposure could be associated with significant changes in pain response, anxiety, locomotor activity and coordination in adult offspring rats.
