This study introduces an anatomical basis for surgeries such as thoracoscopeassisted thoracolumbar spinal anterior interbody fusion in terms of image observing and corpse specimen anatomising. The observation of the 3-dimensional computed tomography (CT) image indicates that segmental arteries are visible and run in the central supersulcus of the corresponding vertebral body’s side, while the branches are invisible. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁, L₁/₂,, and L₂/₃ are 23.35 ± 1.48, 25.61 ± 2.08, 29.12 ± 2.30, 32.53 ± 2.18, and 33.73 ± 2.29 (mm), respectively. And the observation by the thoracolumbar spine side of the adult corpse specimens shows that segmental arteries and veins constantly exist and run in the central supersulcus of the corresponding vertebral body’s side; each segmental artery has some small branches; the zone between the upper and lower segmental arteries form a relatively non-vascular nerve safe zone, where the intervertebral space (disc) locates. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁,L₁/₂,L₂/₃ are 23.34 ± 0.78, 25.54 ± 0.85, 29.11 ± 1.01, 32.82 ± 1.28, and 33.71 ± 1.42 (mm), respectively. The safe zone, with the intervertebral disc as the reference mark, can provide enough operation space for surgeries like thoracoscope-assisted anterior interbody fusion and reducing damage to blood vessels as well as surgical complications. Additionally, the arrangement and distribution of segmental arteries can be clearly displayed on the 3-dimensional CT image and the result is basically consistent with that of corpse specimens. Therefore, the 3-dimensional CT image can be regarded as the reference for video-assisted thoracoscopic surgery plans. (Folia Morphol 2010; 69, 3: 128–133)

Normally the 7th cervical vertebra (C7) has a long non-bifid spine. A bifid spine is a feature of typical cervical vertebrae such as C3–C6. In contrast to past studies, which have described a bifid spine in the C3–C6 cervical vertebrae, this study is a report on the presence of a duplicated spinous process in the C7 vertebra with an intervening space. The presence of such anomalies may be associated with other congenital anomalies and needs a careful and thorough clinical approach. This is an extremely rare finding which may be of clinical interest to radiologists, neurologists, orthopaedic surgeons, anthropologists and forensic personnel. The present case report describes the anatomical details in the bone specimen along with its radiological picture in a case of a duplicated spinous process of the C7 vertebra.

Variations in the configuration of the bony septum found in patients with split cord malformations are rare. We report the seemingly rare occurrence of a midline bony septum that ended posteriorly as a fully formed bony spinous process. We speculate that this variation is due to misplaced mesodermal cells associated with the primitive endomesenchymal tract during approximately the third week of foetal life. The clinician that manages these patients may wish to consider this rare morphology and avoid excessive manipulation of such a process, which could potentially injure an underlying hemicord.

In a randomized study 50 women, aged 51.7±2.8 years, suffering from primary osteoarthrosis (OA), were divided into two, equal groups (I, II). The women were employed in garment industry in contract work system. They were working in compulsory, mainly standing position. The women complained of backache of the lumbar region continuing for the minimum 5 years. During the study, bone mineral density (BMD) of the lumbar spine was assessed twice with the densitometry DEXA method (Lunar Corporation equipment). Before treatment, structural changes in the lumbosacral spine were revealed using a CT Simens Sonata Plus 4. One energy technique (SEQCT) was applied. Concentrations of bone-forming markers in serum were measured three times: before treatment and 3 and 12 months afterwards. The concentration of acid phosphatase in serum was assessed by the enzymatic method according to Hitachi. The concentrations of osteocalcin and procolagen were radoimmunologically assessed by means of DRG Company – sets and concentration basal prolactin (PRL) before treatment radioimmunoassy kits produced by bioMerieux. In the first stage of the treatment, the women in the first group received placebo for three months. Slow Mag B6 was administered for three months to the women in the second group. In the second stage of the treatment, the women in both groups received 21-day therapeutic cycles of modified transdermal hormonal replacement therapy. Additionally, bromocriptine (2.5 mg per day) and Slow Mag B6 (160 mg per day) were administered orally. The cycles repeated at a 7-day interval. During the interval, withdrawal bleeding occurred. The results were statistically assessed by means of computerized programme package Statistica PL, version 5. It was stated that in 60% of women suffering from primary OA the basal concentration of prolactin in serum in was elevated above 25 ng/ml; in 25% women it was on the border level, and in 15% of the patients it was below the lower limit of the normal values. The combined treatment in women suffering from OA caused increase in bone-forming markers and decrease in pathological resorption processes of mineralization of the vertebral bodies. After 12 months of the therapy, resorption in the lumbar spine was diminished compared to the initial values, before the treatment. These changes were significant in L3/L4 vertebral bodies (p<0.05).

Introduction and objective: Back pain are the most common ailment within the human locomotor system. Because of their prevalence, they were classified as diseases of civilization. The aim of the study was to attempt to assess the concentration of selected amino acids in plasma and correlating the results of laboratory tests with the occurrence of backaches. Material and method: The study group included 188 patients presenting for CT scan administering as the cause of their symptoms low back pains. All of these patients gave the blood samples from which the concentration of free amino acids was estimated by ion exchange chromatography using an automated amino acid analyzer AAA 400 from INGOS Praha. The control group consisted of patients who underwent testing using computed tomography and there were no primary or secondary changes associated with degeneration in the lumbar spine. Results: Patients on the basis of research carried out by computed tomography were divided into five groups according to disease entity. Analyzing the average concentration of essential amino acids in the blood plasma of patients of each group, it was found that it is higher in the case of lysine for each considered disease entity. The average concentration of methionine in all disease entities does not deviate from the average values in the control group. Analysis of the average concentration of selected essential amino acids revealed that in the case presented disorders underwent their level of variation. Average concentrations of selected amino acids have proven to be very similar in both groups. Slightly higher values proved to be in the control group for proline and lysine. Conclusions: The concentration of amino acids varies with the severity of degenerative changes in the connections as well as in interbody joints. The highest increase in the concentrations of all tested amino acids are present in root bands. Decrease in the concentrations of all tested amino acids appears in cancer.

The tegument ultrastructure of the intestinal fluke Aphallus tubarium was studied for the first time with the use of scanning and transmission electron microscopy. New details on morphology were recorded. The ultrastructural study revealed that the tegument of A. tubarium had a syncytial organization with a distal cytoplasm lying over a basal matrix and cytons. The surface of the tegument is covered with pectinate spines arranged quincuncially. As anterior-posterior differences were observed, particular attention was given to spines. Spines decrease in size and density from the anterior part of body to posterior part. Two types of sensory structures were identified, uniciliated and dome-shaped. Type 1 sensory receptors were outgrowths bearing groups of papillae with shorter and rigid apical seta visible on the anterior part of body surface, encircling the worm. Type 2 sensory receptors was dome-shaped papillae devoid of cilia, found mainly around the oral sucker. Diagrams of spines and sensory receptors were made to help in understanding the nature of these structures. Surface morphology may prove to be useful in distinguishing Aphallus spp with other Cryptogonimidae.

The objective of the study was the preliminary recognition of whole body mechanical vibration risk among farmers in the rural work environment. The study covered 15 farms using cultivated land of the size of over 10 ha, carrying out mixed production (plant-animal), equipped with agricultural tractors, and a basic set of tractor-mounted agricultural machinery, with a partial contribution of self-propelled agricultural machines. The scope of the study covered the measurements of effective vibration RMS acceleration (equivalent, maximum, minimum, peak) frequency corrected on the seats of agricultural vehicles in the three spatial directions of vibration (X, Y, Z). These measurements were realized while performing various fi eld and transport work activities during the period of the whole year. A analysis of the peak, maximum and minimum vibration accelerations confi rms that in the agricultural occupational environment there occurs a considerable variation of the vibration values registered. This is also evidenced by high values of the Crest Factor, sometimes exceeding a score of 10. Analysis of the registered equivalent values of vibration acceleration (frequency corrected) from the hygienic aspect showed that vibration occurring on the seats may create risk for farmers’ health while performing such work activities as: tedding and raking of hay, fertilizers spreading, soil aggregation, grass mowing and cultivation. Analysis of the spatial distribution of the measured, frequency corrected vibration accelerations indicates that considerably the highest acceleration values occur in the vertical plane (direction – Z). Literature data clearly confi rm an unfavourable effect of whole body vibration present in agricultural vehicles on discomfort and the occurrence of back pain in the operators, especially in the low back region (lumbar spine), as well as degenerative changes in the spine.

Steringophorus arntzi sp. n. is described from notothenioid fishes, Bathydraco marri (type-host, Bathydraconidae) and Dolloidraco longedorsalis (Artedidraconidae). This species resembles S. furciger (Olsson, 1868), but it is distinguished from that by eggs with a short filament, entire ovary (only with irregular margins), less elongate body and a post-bifurcal genital pore. Its area of distribution, the Antarctic, is distant from that of S. furciger (in the north hemisphere). Steringophorus liparidis sp. n. is described from Paraliparis antarcticus (Liparididae). This species resembles S. thulini Bray et Gibson, 1980, but it is distinguished by eggs with a spine on the anopercular pole, longer intestinal caeca, vitelline fields situated more anteriorly in relation to the ventral sucker, different hosts (liparidids contrary to gadiforms) and area of distribution (the Antarctic contrary to the north Atlantic). Occurrence of fellodistomid digeneans in the Antarctic subcontinental waters is recorded for the first time.
