The development of circuli on the scales of young walleye were related to fish size and age. The species first develop scales in the caudal peduncle region of the body when the fish are approximately 30 mm in total body length and about 36 days old. Scale growth and circulus formation are directly related to body growth, with maximum deposition occurring in late July and early August. Seldom are circuli continuous ridges surrounding the scale focus; rather the number of lateral and central circuli are dependent on scale shape, body size, and time. The distances between respective circuli of all age groups examined were relatively constant except for a progressive increase in intercircular spaces between the first four circuli of fish aged 36–64 days. Within each age group the mean intercircular distances between the first 10 to 12 circuli tended to decrease with distance from scale focus. Cteni develop on caudal scales when scales have four to five circuli and when walleye are about 6 weeks of age.

Cutthroat trout were collected periodically from April 3 to September 20, 1968, by electrofishing and were preserved in formalin. Within a few days, each fish was measured and a sample of scales was taken for study. Scales first appeared on these cutthroat trout immediately above and below the lateral line on the anterior portion of the caudal peduncle. Scales were always selected from this area for study, mounted in glycerin–gelatin, and examined at a magnification of 127 diameters. Scales grow relatively more slowly as the fish increases in length, causing the body–scale relation to be curvilinear. Growth of the fish was determined both by calculating size-at-age data from the scales and by comparing mean lengths of age-groups collected at different times of the year.The growth of cutthroat trout from Chef Creek was slow; calculated mean fork lengths for the first three annuli were 50, 84, and 119 mm. Only a few fish of age-group IV were collected and these were considered to be nonanadromous individuals on the basis of scale examination and small size.

Sixty specimens of singing catfish Trachelyopterus striatulus (Steindachner, 1877) (Siluriformes: Auchenipteridae) collected from Guandu River (22º 48' 32" S and 43º 37' 35" W), in the state of Rio de Janeiro, Brazil from October 2006 to March 2009, were necropsied to study their parasites. From the 60 specimens of T. striatulus examined 57 were parasitised by at least one parasite species. The majority of the parasite specimens collected were monogeneans followed by Nematoda, Digenea and Hirudinea. Cosmetocleithrum sp. was the numerically predominant species with highest prevalence and abundance. The parasites of T. striatulus showed the typical pattern of aggregated distribution. No parasite species showed significant correlation between the body total length of the host and their abundance. The mean parasite species richness was not correlated with the host's total body length and sex. Values of the Brillouin index of diversity had a mean of H = 0.083 ± 0.136.

Background: Goat husbandry has been playing an important role in the economy of our country with special reference to milk, meat, manure and hide production. Bakerwali goat constitutes about 50% of the total goat population of J and K. The liver is an extremely important organ in the body of mammals performing numerous functions. The liver is much heavier in young animals than older animals as it atrophies with age. The present study has been planned to record the micrometrical data about the liver of Bakerwali goat during different age groups. Methods: Liver samples were collected from slaughter houses of Nagrota in and around Jammu city of UT of J and K during 2019-20. The samples were divided into young (below 1 year), adult (2-3 years) and senile (4 years and above) as per the dentition of the goats. Six samples from each age group were collected. The micrometrical observations were recorded on H and E stained sections with the help of an ocular micrometer duly calibrated with stage micrometer. Result: The capsule showed maximum thickness in adults followed by the young and senile age group. The maximum thickness of the capsule was seen at upper part of main lobe (UPOML) in the liver of young and adult whereas, in the senile group, the maximum thickness was seen at middle part of main lobe (MPOML). The diameter of the central vein showed the highest values in adults, followed by young and senile probably due to increased liver functions in adult. The mean values of length of hepatocytes ranged between 13.50 to 22.50 µm in all regions of the liver of irrespective of age groups. The mean values showed higher values in adult and senile age groups. The nuclear diameter of the hepatocytes ranged between 9.00 to 13.50 µm with mean values varying between 9.72±0.58 to 10.05±0.50 µm in all the three age groups. The maximum number of portal triads per field was seen at ventral part of main lobe (VPOML) in the senile group whereas the minimum number was observed at MPOML in the young group. In general, several portal triads per field were highest in the senile group followed by adult and young.

Aim: The study aims to analyze the specific gravity with the hemoglobin of the blood. Introduction: The ratio of the density of a substance to the density of the water at a specified temperature and pressure is known as specific gravity. Blood is a fluid connective tissue that delivers oxygen and nutrients to the cells and transports metabolic waste away from the cells. Red blood cells are biconcave disc-shaped cells produced from bone marrow. It contains proteins that transport oxygen from the lungs to all the parts of the body. The term heme reforms to the iron-containing porphyrin. The aim of the study was to analyse the specific gravity of Hemoglobin of the blood. Materials and Methods: 10 random blood samples were collected from the patients in Saveetha Dental College. Then the samples were centrifuged and the blood-specific gravity and hemoglobin were analyzed from the sample using a multi-reagent strip and the specific gravity and hemoglobin was determined. Results and Discussion: The mean specific gravity value of age group 21 - 30 years is 1.015, the mean specific gravity value of age group 31 - 40 years is 1.018, the mean specific gravity value of age group 41 - 50 is 1.016, and the mean specific gravity value of age group more than 50 years is 1.020. The mean specific gravity value of females is 1.01750 and the mean specific gravity value of males is 1.01750. The mean Hb value of females is 11.67 and the mean Hb value of males is 14.68. Conclusion: The value of mean specific gravity is slightly increased among different age groups and the mean Hb value is also slightly increased with different age groups. Between genders mean specific gravity is equal to both genders and mean Hb value is more in males compared with females.

Abstract Background Early diagnosis and treatment of ACS can reduce the risk of complications and death. Delay calling for help can increase morbidity and mortality. It is unclear which age group among patients with acute coronary syndrome tend to delay their call for help. Results Our observational retrospective study showed that men and women in their 50s and 40s respectively tend to delay their call for help from symptoms onset. For the former, the mean time delays (590 ± 71.1 min), whereas for the latter it was (1084 ± 120.1 min). Moreover, these groups tend to have a longer time delay between symptoms onset and arrival at the hospital. Among deaths, we observed that the death rate was proportional to the time delay, which is not unexpected. Next step, we plan to perform a qualitative study in the form of questionnaires to target the individuals with a high risk of CVD within these age groups. Conclusion Middle age group of both genders tend to delay their call for help when they experience symptoms of ACS; moreover, regardless of the age, the longer the delay, the higher the mortality rate. The results of this study gave us a better understanding of our local population and will pave the road for a well-structured teaching programme for them to minimise the time delay for calling for help.

ABSTRACT: The aim of this research was to measure the intraocular pressure (IOP) of normal chinchilla eyes using the rebound tonometer. A further aim was to assess whether there were differences in the values of intraocular pressure in relation to animals age, gender and time of day. Thirty-six chinchillas were divided into three groups of 12 chinchillas each, by age: Group I (2-6-month-old), Group II (20 and 34 months) and Group III (37 and 135 months). Ophthalmic examination was performed previously by Schirmer tear test, slit lamp biomicroscopy, indirect ophthalmoscopy and fluorescein test in all chinchillas. Three measurements of intraocular pressure were assessed on the same day (7, 12 and 19h). Tonometry was performed on both eyes using the rebound tonometer after calibration in "p" mode. Statistical analysis was performed with SigmaPlot for Windows. The mean IOP for groups I, II and III were 2.47±0.581mmHg, 2.47±0.581mmHg and 2.51±0.531mmHg, respectively. No significant differences were reported between age and IOP and no significant differences were reported between the time of day and IOP. The IOP in chinchillas did not differ significantly between genders or ages of the animals, and did not change with time of day.

Abstract Background Injury is one of the major public health problems, which causes more than 5 million deaths in the world every year. Cases of specific types of injury put a tremendous threat to human health and also add a heavy medical burden on individuals and societies. This study was to calculate and analyze the current curative expenditure (CCE) of injury in Dalian and consequently to provide control strategies for decision-makers. Main text: A total of 565 medical institutions were selected with multistage stratified cluster random sampling, containing 4,375,351 valid samples. Subsequently, the distribution of injury CCE in different dimensions (including age and site of injury) was analyzed under the framework of System of Health Accounts 2011(SHA 2011) using the established database. There were increases from 32.36/100,000 in 2006 to 37.34/100,000 in 2017 and from 46.12/100,000 in 2006 to 54.48/100,000 in 2017 in urban and rural residents respectively. The study found that the CCE of injury in Dalian had reached 1572.73 million RMB, accounting for 7.45% of the total curative care expenditure. In the 15–25 age group, the cost of injury accounts for a larger proportion of CCE than other age groups. Among the injuries in different regions of the body, injuries to the spine, lower limb, head and foreign body entering cost the most. Conclusions Dalian has a relatively serious burden of injury costs. The essential and primary goal is to reduce the cost and increase the benefit of attending to patients with injuries. Specific control strategies should be tilted toward the age group 15–25. Injuries to the spine, lower limb, head and foreign body entering also should be priorities of interventions.

Ayurveda is a science of life, which mainly aims to promote and preserve the health of the individuals. In this techno and competitive era, life style and diet are major factors influencing the health of the individuals. Diet and dietary habits play important role in maintenance of health. Ayurveda, its main aim is to promote and preserve the health, strength and longevity of healthy person and to cure the disease. Ayurveda places special emphasis on Ahara and believes that healthy nutrition nourishes the Sharir, Mana, Atma. As Acharyas has described Ahara. Nidra, Brahmcharya are Tryoupsthambha (sub pillars) which support the body itself. Here Ahara has been placed first which shows that it is most important to maintain and sustain of life. Children are delicate and most sensitive and prone to the infectious diseases. They are miniature of adult. They are in Ajatvyajanawastha (developing stage). Psychologically they are innocent. Being in developmental phase, Ahara plays very important role in the life of children. So parents should be aware of dietetic components required by child in different age groups.

 Background: Acute appendicitis is very common surgical cause of acute abdomen and needs surgical removal either by laparoscopic or open appendicectomy. The aim of this study is to compare frequency of surgical site infection (SSI) in patients undergoing laparoscopic and open appendicectomy. Materials and Methods: The study was prospective study conducted in NMCTH, Biratnagar. Total 200 patients with diagnosis of acute appendicitis admitted through the emergency department of our hospital were included in the study. The patients were randomly allocated in two groups: Laparoscopic appendicectomy group (LA) and Open appendicectomy group (OA). Both groups underwent successful emergency appendicectomy. Wound infections in terms of surgical site infection (SSI) if present were recorded. All age groups and both sexes were included.  Results: Two hundred patients underwent appendicectomy, one hundred Laparoscopic appendicectomy (LA) and another hundred open appendicectomy (OA). The mean age of patients with acute appendicitis was 30.63±16.14 years with minimum of 6 years and maximum of 77 years. The highest number of patients were in age group of 10 to 20 years (29.5%). In LA group SSI noted in 3 patients (3%) whereas in OA group it was found in 12 patients (12%). Conclusion: Laparoscopic appendicectomy is better and offers great advantages in terms of SSI as compared to Open appendicectomy.
