Remove any bubbles of air from the syringe by holding it with the needle facing upward and gently tapping on the syringe so that the air moves to the top of the syringe discount viagra 75 mg amex erectile dysfunction in 60 year old. Gently push the plunger until a small drop of liquid reaches the tip of the needle cheap viagra 100mg with mastercard erectile dysfunction depression medication. The prescribed dose of Ovidrel PreFilled Syringe 250 mcg is ready for administration. A subcutaneous injection involves depositing medication into the fatty tissue directly beneath the skin using a short injection needle. The needle is inserted at a 90 degree angle to the skin unless you were instructed otherwise. The most convenient sites for subcutaneous injection are in the abdomen around the navel or upper thigh. Selecting an area for an subcutaneous injection will depend on directions from your doctor and medication’s instructions. You should choose a different site for each new injection—rotate your injection site as recommended by the manufacturer. The site you choose for your frst injection does not matter, as long as the initial site is in an appropriate area. Prior to giving the injection, clean the injection site with an alcohol wipe starting at the puncture site. Hold syringe in your dominant hand between your thumb and fnger as you would a pencil. Insert the needle into the skin of the pinched area at a 90 degree angle to the skin, unless you were instructed otherwise, (using a quick dart like motion) to ensure that the medication is deposited into the fatty tissue. After the needle is completely inserted into the skin, release the skin that you are pinching. Depress the plunger at a slow, steady rate until all the medication has been injected. Once the medication has been administered, dispose of the needle and syringe in the sharps container. Medication information Ovidrel PreFilled Syringe (choriogonadotropin alfa • pregnancy outside of the uterus injection) • breast pain This drug is usually given to women who want to get pregnant. Other side • body pain effects are injection site bruising, pain after surgery, stomach • back pain pain, nausea and vomiting. Medication information • mood changes Other side effects include the following: • trouble sleeping • problems with the stomach or intestines • upper respiratory tract infection • injection site bruising • cough • injection site reaction • painful urination • ovarian cysts • urinary tract infection • ovarian hyperstimulation • urinating by accident • stomach pain • protein in the urine • injection site infammation • irregular heartbeat Other less common side effects include the following: • vaginal yeast infection • genital herpes • breast pain • high white blood cell count • gas • heart murmur • swollen stomach • cervical cancer • sore throat For those taking this drug to make eggs without other fertility • upper respiratory tract infection treatment, the most common side effects are injection site • high blood glucose (sugar) problems, injection site pain and problems with the sex organs. Medication information Serious Side Effects Some patients taking this drug have had miscarriage. Call your doctor right away if you have any of Speak with your doctor for information about the risks the following symptoms: and benefts of available treatments. Medication information • pituitary tumor or other brain tumor • unusual uterine bleeding • ovarian cysts or enlarged ovaries • sex hormone-dependent tumors in or around the sex organs • known or suspected pregnancy Tell your doctor if you are breastfeeding. Select a location for your supplies with a surface that is clean and dry such as a bathroom or kitchen counter or table. Wipe the area with antibacterial cloth or put a clean paper towel down for the supplies to rest on. Clean the rubber stopper with an alcohol wipe and let dry each time you use the medication. Assure that the mixing needle is securely attached to the syringe by twisting it to the right, or clockwise onto the top of the syringe (needles that are attached by the manufacturer are often not frmly secured). Remove the protective cap from the syringe, being careful not to touch the syringe tip. Pull the syringe plunger back to the unit mark your physician has instructed you to administer. Insert the needle into the rubber stopper on the medication vial and push the plunger to gently force air into the vial. Without removing the needle from the vial, and while holding the vial and needle up straight, gently tap the syringe so that any air bubbles rise to the top of the syringe. Push the bubbles of air back into the vial and pull back on the plunger to assure that you have the accurate dose of medication in the syringe. Remove the injection needle from its sterile packaging and attach it to the syringe by twisting it to the right, or clockwise. Remove the needle cap by pulling upward only when you are prepared to administer the injection. An intramuscular injection involves depositing medication into deep muscle tissue using a longer injection needle. Injection sites typically include the mid-thigh or upper, outer quadrant of the buttocks. Prior to giving the injection, clean the injection site with an alcohol wipe starting at the puncture site, using frm pressure and working your way outward in a circular motion about two inches. Hold the syringe in your dominant hand between your thumb and fngers like you hold a pencil. Try to relax the muscle you will be injecting as injecting into tense muscles will be more painful. Holding the syringe straight up at a 90 degree angle to the skin from the injection site, insert the needle using a quick motion. Note: The step of slowly “pulling back” on the plunger of the syringe to see if blood fows into the syringe is specifc to how you were instructed to give yourself an injection. It is important that you understand and follow your medication’s specifc instructions. Depending on what your doctor told you to do, please see section A and B on the following step for more information. Remove the needle quickly, and apply pressure to the injection site with a gauze pad, if needed. Remove the needle from the injection site, and frmly press the injection site with a gauze pad for a few seconds, if needed. Once the medication has been administered, dispose of the needle and syringe in the sharps container. Medication information progesterone injection • acne This drug is given to women whose bodies do not make enough • hair loss progesterone. Your doctor will teach you bleeding, breast lumps or yellowing of the skin or eyes. Speak with your doctor for information about the risks Always follow the instructions provided by your doctor.

The Physiology of Metabolism and Growth in Bacteria 161 reactions buy viagra canada erectile dysfunction talk your doctor, the energy requirement is consumed in the form of light or chem- ical energy—by photosynthetic or chemosynthetic bacteria buy viagra line green tea causes erectile dysfunction, respectively. Catabolic reactions supply both energy and the basic structural elements for synthesis of specific bacterial molecules. Bacteria that feed on inorganic nutrients are said to be lithotrophic, those that feed on organic nutrients are organotrophic. Human pathogenic bacteria are always chemosynthetic, organo- trophic bacteria (or chemo-organotrophs). Bacterial exoenzymes split up the nutrient substrates into smaller molecules outside the cell. Nutrients can be taken up by means of passive diffusion or, more frequently, specifically by active transport through the membrane(s). The substance to which the H2 atoms are transferred is called the hydrogen acceptor. In anaerobic respira- tion, the O2 that serves as the hydrogen acceptor is a component of an inor- ganic salt. The main difference between fermentation and respiration is the energy yield, which can be greater from respiration than from fermentation for a given nutrient substrate by as much as a factor of 10. Fermentation processes involving microorganisms are designated by the final product, e. The energy released by oxidation is stored as chemical energy in the form of a thioester (e. Anaerobic respiration is when the electrons are transferred to inorganically bound oxygen. Oxygen is activated in one of three ways: & Transfer of 4e– to O, resulting in two oxygen ions (2 O2–). The Physiology of Metabolism and Growth in Bacteria 163 Bacteria are categorized as the following according to their O2-related behavior: & Facultative anaerobes. These bacteria can oxidize nutrient substrates by means of both respiration and fermentation. Their metabolism is adapted to a low redox potential and vital enzymes are in- 3 hibited by O2. These bacteria oxidize nutrient substrates with- out using elemental oxygen although, unlike obligate anaerobes, theycan tol- erate it. The principle of the biochemical unity of life asserts that all life on earth is, in essence, the same. Thus, the catabolic intermediary metabolism of bacteria is, for the most part, equiva- lent towhat takes place in eukaryotic cells. The reader is referred to textbooks of general microbiology for exhaustive treatment of the pathways of inter- mediary bacterial metabolism. Anabolic Reactions It is not possible to go into all of the biosynthetic feats of bacteria here. Some bacteria are even capable of using aliphatic hydrocarbon compounds as an energy source. It is hoped that the metabolic capabilities of these bacteria will help control the effects of oil spills in surface water. Bacteria have also been enlisted in the fight against hunger: certain bacteria and fungi are cultivated on aliphatic hydrocarbon substrates, which supplycarbon and energy, then harvested and processed into a protein powder (single cell protein). Culturing of bacteria in nutrient mediums based on methanol is another approach being used to pro- duce biomass. One form such control activity takes is regulation of the activities of existing enzymes. Many enzymes are allosteric proteins that can be inhibited or activated by the final products of metabolic pathways. One highly economical type of regulation controls the synthesis of 3 enzymes at the genetic transcription or translation level (see the section on the molecular basis of bacterial genetics (p. Growth and Culturing of Bacteria Nutrients The term bacterial culture refers to proliferation of bacteria with a suitable nutrient substrate. Other necessities include sources of carbon and nitrogen for synthesis of specific bacterial compounds as well as minerals such as sul- fur, phosphorus, calcium, magnesium, and trace elements as enzyme activa- tors. Nutrient agar liquefies when heated to 1008C and does not return to the gel state until cooled to 458C. Selective mediums Contain inhibitor substances that allow only certain bacteria to proliferate. The Physiology of Metabolism and Growth in Bacteria 165 Growth and Cell Death Bacteria reproduce asexually by means of simple transverse binary fission. The time required for a reproduction cycle (G) is called the generation time (g) and can vary greatly from species to species. Fast-growing bacteria cultivated in vitro have a gen- eration time of 15–30 minutes. Obligate anaerobes grow much more slowly than aerobes; this is true in vitro as well. Of course the generation time also depends on the nutrient con- tent of the medium. The so-called normal growth curve for bacteria is obtained by inoculat- ing a nutrient broth with bacteria the metabolism of which is initially quies- cent, counting them at intervals and entering the results in a semilog coor- dinate system (Fig. The lag phase (A) is characterized by an increase in bacterial mass per unit of volume, but no increase in cell count. During this phase, the metabolism of the bacteria adapts to the conditions of the nutrient medium. In the following log (or exponential) phase (C), the cell count in- creases logarithmically up to about 109/ml. This is followed by growth decel- eration and transition to the stationary phase (E) due to exhaustion of the nutrients and the increasing concentration of toxic metabolites. The generation time can only be determined dur- ing phase C, either graphically or by determining the cell count (n) at two different times and applying the formula: t2 À t1 g ¼ : log2 n2 À log2 n1 Normal Growth Curve of a Bacterial Culture Fig. F A B (Hours) Time (Days) Kayser, Medical Microbiology © 2005 Thieme All rights reserved. The number of living cells in a given culture or material can be determined by means of the colony counting method. Using the pour platetechnique, each dilution is mixed with 1 ml of liquid agar and poured out in a plate. The simplest way to determine the mass is by means of photometric ad- sorption measurement. The increases in mass and cell count run parallel during phase C on the growth curve. The Molecular Basis of Bacterial Genetics & Bacteria possess two genetic structures: the chromosome and the plas- mid. Noncoding interposed sequences (introns), like those seen in eukaryotes, are the excep- tion. The phases of transcrip- tion are promoter recognition, elongation, and termination. Many genes that code for functionally related polypeptides are grouped together in chro- mosome or plasmid segments known as operons.
